Data visualization tools compared: which one fits your marketing data?

Choose a data visualization tool on the question you answer each month, not features.

The number of chart types barely matters.

What matters is whether the tool shows where your clients come from and what they bring in.

The verdict: for most B2B teams, a free dashboard tool like Looker Studio is more than enough. Power BI comes into play once you connect several channels and a CRM.

Tableau only pays off with real volume and your own data team.

Datawrapper and Flourish are publication tools for beautiful charts, not steering instruments.

Rule of thumb: choose on connectivity and on what you need to decide, not on the “wow factor” in the demo.

A beautiful chart that steers nothing is a waste.

Below we line up the best-known data visualization tools and say when each one fits.

What does a data visualization tool actually do?

It turns raw numbers into a visual overview you can read in seconds.

Think sessions, leads, conversions and revenue. Salesforce describes data visualization as presenting information so people can understand it and act on it.

The good tools connect to your data sources and turn them into:

• interactive charts
• maps
• dashboards you click through

Simpler option: only want to go through a raw export yourself? Then a pivot table for marketing data is often enough.

Why a built-in report isn’t a dashboard

Every platform already has its own reports.

They answer one question, inside one tool.

Here’s our own GA4 traffic acquisition report, filtered on one source:

Our own GA4 property for customerimpact.be, session source report filtered on chatgpt.com, 90 days to October 2026.

That’s 58 sessions and 1 key event.

Useful, but it says nothing about what those visitors became in your CRM.

A dashboard tool puts that source next to your ads, your Search Console data and your deals.

How to read it: our guide to tracking ChatGPT traffic in GA4 walks through this report.

Two kinds of tools that people mix up

There’s an important split in the market. Many buyers miss it:

• Dashboard tools: Looker Studio, Power BI and Tableau connect live data for steering
• Publication tools: Datawrapper and Flourish make polished, standalone charts to publish

Dashboard tools build reports you click through.

They’re the tools behind your monthly marketing decisions.

Publication tools: they produce charts for your website, a blog or a presentation.

Great for telling a story, but not for running your business.

That difference already decides half of your choice. Do you want to steer something, or show something?

Which data visualization tools are there, and where do they shine?

Five tools cover almost every B2B need. Here they are side by side, with what each is made for.

Prices sit on very different levels.

Here’s what one user costs per month at the entry level of each paid plan:

The gap is large.

Five Tableau Creators cost $375 a month, while five Looker Studio users cost nothing.

1. Looker Studio

Google’s free dashboard tool, and the logical starting point for most B2B teams.

Best for: teams whose data lives mainly in Google products.

Biggest strength: it connects seamlessly with Google Analytics 4, Google Ads and Search Console.

Price: free. Google’s documentation now calls it Data Studio, “a no-cost tool” for dashboards and reports (checked 20 October 2026).

Watch out: blending non-Google sources, such as a CRM, often needs a paid connector or a spreadsheet in between.

There are no license costs, and you share reports with a link.

Search Console is one of those native sources:

Search results performance in our own Search Console for customerimpact.be, last 28 days to mid October 2026.

In Looker Studio, those same clicks and positions sit next to your GA4 leads in one report.

Setting it up step by step is in our guide to Looker Studio.

2. Power BI

Microsoft’s tool, and it shines in connectivity.

Best for: teams that combine spreadsheets, GA4, ad platforms and a CRM.

Biggest strength: it brings standalone sources together in one interactive report.

Price: Power BI Desktop is a free download. Pro costs $14 per user per month and Premium Per User $24, both paid yearly (checked 20 October 2026).

Watch out: sharing needs a paid plan. The free account says: “Upgrade to Pro or Premium to share reports.”

So you build for free, but everyone who views a shared cloud report needs a license.

More on this in our article on Power BI for marketers.

3. Tableau

A best-in-class business intelligence tool with strong visualization power.

Best for: larger organizations with big datasets and a data team.

Biggest strength: an intuitive interface that drills into almost any data source, with enterprise-level governance (according to the vendor).

Price: role-based. A Creator costs 75 dollars per user per month in the Standard edition (according to Tableau). Explorer and Viewer roles cost less.

Watch out: count on a recurring cost per employee. Tableau’s pricing page blocked our recheck, so this is its last published list price.

The Creator license is the one you build reports with. Explorer and Viewer roles mainly view and click through.

Free options: there’s also a free “Public” version and a 14-day trial.

Want to look beyond visualization alone?

Then compare the broader business intelligence tools on the same four factors below.

4. Datawrapper

Not a BI tool, but a publication tool for interactive and responsive charts, maps and tables.

Best for: content teams that publish data in articles and reports.

Biggest strength: it makes complex data readable. Newsrooms like The New York Times use it (according to the vendor).

Price: the free plan lets you create, publish and embed charts, maps and tables. Pro costs $21 and Business $39 per user per month, excluding VAT (checked 20 October 2026).

Watch out: a custom theme in your own branding is an add-on at $499 per month, excluding VAT.

The free version is fine for internal use.

That’s a different pricing story than a dashboard tool.

5. Flourish

Flourish plays in the same corner as Datawrapper.

Best for: narrative, often animated visuals in a blog or presentation.

Biggest strength: making a point with data storytelling.

Price: the free plan includes “Public publishing and embedding, with attribution”. Paid plans run through Canva or sales, without public prices (checked 20 October 2026).

Watch out: strong for making a point, not for following your numbers every day.

How do you choose the right data visualization tool?

Forget the feature list for a moment. The choice comes down to four things.

Connectivity: does it connect with your data?

This is the most important factor.

No tool is good enough to justify a data migration.

You need something that connects with your data wherever it lives:

• your GA4 property
• your ad platforms, such as Google Ads
• your CRM

If a tool doesn’t connect smoothly, you end up copying and pasting every month.

That’s exactly where errors and delays creep in.

Tip: check in advance whether the sources you use are officially supported.

For Google Ads, that starts with how you link GA4 to Google Ads.

What do you really need to decide?

Start with the question you answer every month. For B2B it’s almost always a pair:

• where do my leads and clients come from?
• what’s their conversion rate and eventual revenue?

You aren’t selling through a webshop where every pageview counts.

You have a handful of valuable leads per week.

What you need: not a tool that can do a hundred charts, but one that shows the ten to twelve numbers that truly matter.

For example, say you sell software to logistics firms. Your monthly view then needs four numbers:

• leads per channel
• cost per lead
• deals won
• revenue per source

Go deeper: how you make that selection is in our piece on the marketing dashboard.

The KPIs themselves are in our list of B2B marketing KPIs.

Rule of thumb: if a chart doesn’t change a decision, leave it out.

Skill: who is going to work with it?

Tableau and Power BI can do a lot.

But with complex data flows you want someone in house who manages them.

Easier start: Looker Studio and the publication tools suit non-specialists. Drag and drop, and you’re up and running the same day.

Be realistic about your team.

Watch out: a powerful tool no one maintains delivers less than a simple tool that actually gets used.

Dashboard or publication?

Finally, come back to that first split. For example, a monthly budget meeting and a blog chart need different tools:

Don’t confuse the two. A publication tool as a daily steering instrument is frustrating.

And a BI tool to share a single chart is shooting a fly with a cannon.

Ad reporting: for Google Ads specifically, see our guide to Google Ads reporting.

What’s our recommendation for B2B?

For most Belgian B2B teams: start for free with Looker Studio.

It connects with your Google data and costs nothing. It also forces you to think about which numbers you show.

Here’s the path we usually see:

If you grow toward multiple channels and want to add your CRM, Power BI is the logical next step.

Tableau only when you really have volume and a data team.

For a small team it’s overkill and a hefty cost.

The tool is the smallest part of the work

That’s the data analytics reality.

A beautiful dashboard on polluted data gives you false confidence.

Order: first a clean tracking foundation, then visualize.

A conversion tracking audit shows whether your numbers can be trusted.

Common trap: we too often see teams stare for months at a gorgeous report that steered on the wrong numbers.

Usually those were vanity metrics: reach and pageviews instead of leads and revenue.

Close the loop with sales

The strongest dashboards show what happens after the form. That needs deal data from your CRM.

Our explainer on closed-loop reporting shows how to feed it back.

Frequently asked questions about data visualization tools

Which data visualization tool is free?

Looker Studio is completely free and connects seamlessly with Google data. Power BI lets you build for free in the Desktop app, but sharing requires a paid plan (according to Microsoft). Datawrapper and Flourish have free tiers for basic use.

Is Tableau worth it for a small business?

Usually not. Tableau is built for large organizations with lots of data and is a considerable investment: you pay per user per month, and a Creator license in particular adds up quickly. A small B2B team is almost always better off with Looker Studio.

What is the difference between a dashboard tool and a publication tool?

A dashboard tool (Looker Studio, Power BI, Tableau) connects live data and helps you steer and click through. A publication tool (Datawrapper, Flourish) creates standalone charts to publish in content or presentations. You use the first to decide, the second to show.

Which tool do I choose if I want to track my marketing and revenue?

A dashboard tool that connects with your CRM and ad platforms. For most teams that’s Looker Studio or Power BI. The tool matters less than the choice of which numbers you show: steer on leads and revenue, not on pageviews.

Is Looker Studio the same as Google Data Studio?

Yes. Google renamed Data Studio to Looker Studio, and its documentation now calls it Data Studio again.

Ready to finally let your data steer?

The tool is the easy part.

The real work is a clean tracking foundation and the right choice of numbers.

Then your dashboard steers on clients and revenue, not on noise.
