How to Visualize Vendor Scorecards in Google Slides Using a Radar Chart

Picture this. You're wrapping up a massive vendor selection process. You've sat through six different sales pitches, read dozens of technical docs, and finally scored each vendor on a scale of 1 to 10 across five categories: Cost, Security, Features, Usability, and Support.

You put all those numbers into a neat little spreadsheet table. Then you show it to your boss.

Their eyes glaze over immediately.

Numbers on a grid don't tell a story. When you're trying to convince a room full of stakeholders why Vendor A is a better partner than Vendor B, you need them to see the difference instantly.

That's where radar charts (often called spider charts) completely change the game.

Why Radar Charts Work for Vendor Scorecards

A radar chart plots multiple dimensions on a single graphic, starting from a central point and expanding outward. Instead of comparing boring rows of data, you're comparing shapes.

If Vendor A is incredibly cheap but has terrible support, their shape leans heavily to one side. If Vendor B is a well-rounded, premium option, their shape fills out a larger, more balanced area on the chart.

It takes the human brain about three seconds to look at two overlapping shapes and say, "Oh, the blue one covers way more ground. Let's go with them."

The Problem with Native Google Slides

If you've ever tried to build a radar chart natively in Google Slides, you know it's incredibly frustrating.

Why? Because the platform simply doesn't offer one.

Most people resort to a terrible workflow: building a spider chart in Excel, taking a blurry screenshot, and pasting it into their slide deck.

But what happens when Vendor C suddenly drops their price by 20% an hour before your big presentation? You have to go back to Excel, update the source file, take a new screenshot, delete the old one, paste the new one, and meticulously resize it. It’s a massive waste of time.

Creating Updatable Radar Charts with ExtraChart

I built ExtraChart specifically to fix workflow headaches like this. We give you a massive library of advanced visualizations—including beautiful, professional radar charts—without ever forcing you to leave Google Slides.

Here’s exactly how you can build a dynamic vendor scorecard today.

Step 1: Pick your chart

First, open up your presentation. Go to Extensions -> ExtraChart -> Create & Edit Charts. The add-on pops open as a sleek sidebar right over your slide. No new tabs required. Simply click on the Radar Chart icon.

Step 2: Drop in your scores

Our popup editor has a built-in, lightweight data interface on the "Data" tab. You don't need to mess around with linking external files. Just copy your vendor scores from Google Sheets or Excel and paste them directly into the editor cells. You'll see your radar chart update instantly on the left side of your screen.

Step 3: Make it look professional

Head over to the "Settings" tab. Here, you have total control over how the scorecard looks.

Want the gridlines to be dotted? Done. Want to change the font to Inter so it matches your brand guidelines perfectly? Easy. You can even tweak the opacity of the shapes so that when Vendor A overlaps Vendor B, your data remains totally legible.

Step 4: Insert and present

Hit "Create" and ExtraChart drops a crisp, high-resolution image right onto your active slide.

The absolute best part? It’s completely updatable. If a vendor's score changes right before the meeting, just click the chart on your slide, re-open ExtraChart, and tweak the number. The add-on retrieves all your settings and regenerates the chart automatically. No more taking screenshots.
