The 5 Best Google Slides Add-Ons to Create Dynamic Funnel, Radar, and Heat Map Charts

March 14, 2026

We've all been there. You have a massive presentation tomorrow morning.

You need to show the latest sales conversion drop-off, so you open Google Slides, click "Insert Chart," and look for a funnel chart.

It's not there.

You look for a radar chart to show a skills assessment. Nothing. A heat map? Not a chance. Native Google Slides is fantastic for basic bar and pie charts, but the moment you need advanced data visualization, it leaves you hanging.

Instead of hacking together a bunch of shapes that you'll have to manually resize every time the data changes, you need a dedicated tool.

Here are the 5 best Google Slides add-ons for creating dynamic funnel, radar, and heat map charts without pulling your hair out.

1. ExtraChart (The Ultimate All-in-One Solution)

I might be a bit biased since this is the AddonsChef blog, but ExtraChart is exactly why we built this tool. We were tired of leaving Google Slides just to make a decent funnel chart.

ExtraChart lives right inside your sidebar. You open it, pick from 20 specialized chart types, and get to work.

Need a radar chart for a brand perception analysis? It's a single click. Need a heat map to show data density? We've got it.

The best part is the built-in data editor. You can copy and paste directly from Excel or Google Sheets. The chart updates in real-time in the preview window. When you hit "Create," it drops a crisp, high-resolution image right onto your slide.

Even better: if your boss asks you to update the numbers right before the meeting, just select the chart, re-open ExtraChart, and edit the data exactly where you left off. No other tool handles updates this smoothly.

2. Lucidchart Diagrams

Lucidchart is a powerhouse for diagramming. If you need to build process flows, org charts, or mind maps, it’s brilliant.

They have a Google Slides integration that lets you pull in your saved diagrams.

While it's not a native "chart builder" in the traditional sense (you have to build the visuals in their external app first), you can technically create funnel graphics and radar web diagrams using their shape libraries.

The downside? It's entirely manual. Your shapes won't dynamically scale based on data inputs, making it tedious if your numbers change frequently.

3. Vizzlo

Vizzlo is a solid visualization platform that focuses on making beautiful, high-end graphics for business professionals.

They offer a massive portfolio of chart types, including the elusive funnel and radar charts. Their Google Slides add-on is polished and gets the job done well.

The main catch with Vizzlo is the pricing and workflow. It can get expensive for individual users, and the interface sometimes feels a bit heavy when you just want to knock out a quick visual for a weekly meeting.

4. Supermetrics

This one is specifically for the marketers out there.

Supermetrics is famous for pulling live data from platforms like Facebook Ads, Google Analytics, and HubSpot directly into your spreadsheets and presentations.

If you need a heat map or funnel chart based exclusively on live marketing data, their tools can help you generate them automatically.

However, Supermetrics is overkill if you just have a quick set of numbers you want to visualize. It's built for complex, automated reporting rather than ad-hoc presentation building.

5. Infogram

Infogram makes gorgeous infographics. If you are building a highly visual pitch deck and want charts that look like they belong in a glossy magazine, this is a great choice.

They support an impressive range of charts, including radar (spider) charts and funnels.

The drawback is that you have to create everything on the Infogram website. Once you're done, you use their integration to push the final image to Google Slides. It breaks your workflow slightly, but the visual payoff can be worth it for major presentations.

Why You Should Keep Your Workflow Native

Switching tabs kills your momentum. When you're trying to nail down the narrative of your presentation, jumping between external websites, spreadsheets, and Google Slides is a massive distraction.

That's why a tool like ExtraChart makes such a difference.

You stay inside Google Slides. Your data stays private (ExtraChart uses 100% client-side rendering). You get full control over layout, typography, and color palettes without ever opening another browser tab.

Stop manually drawing triangles and calling them funnels. Give ExtraChart a spin and see how easy presentation design is supposed to be.
