Radar Chart Maker

Compare profiles across many dimensions

A radar chart, also called a spider or web chart, plots each variable on its own spoke and connects the values into a polygon, so you can read the overall shape of a profile at a glance. InstaCharts is a free radar chart maker that overlays multiple profiles for easy comparison.

What data you need for a radar chart

Spokes A category column; each category becomes one spoke
Values Numerical values plotted along each spoke
Breakdown A category column; each unique value becomes a polygon

Paste your spreadsheet, upload a CSV or Excel file, or connect a Google Sheet, and InstaCharts detects your column types and builds the radar chart automatically.

When to use a radar chart

  • Compare strengths and weaknesses across several attributes
  • Visualize skill or competency scores for a person or team
  • Contrast feature ratings across multiple products
  • Overlay before and after profiles to show change

When another chart fits better

  • Precise value reading is hard; use a bar chart when exact numbers matter
  • More than two or three overlapping polygons get muddy
  • Variables on very different scales need normalizing first

Radar Chart maker FAQ

Is the radar chart maker free?

Yes. Creating and exporting a radar chart is free with no account. The free tier supports up to 500 rows and adds a watermark; paid plans from $10/month remove it.

How many variables should a radar chart have?

Radar charts work best with three to ten variables. Fewer than three does not benefit from the radial layout, and more than ten spokes becomes crowded and hard to read.

What data do I need for a radar chart?

A category column for the spokes and a numeric column for the values. Add a breakdown column to overlay multiple profiles, such as different people, teams, or products.

Why do my values look distorted?

If variables sit on very different scales, one spoke can dominate the shape. Normalize the values to a common range first so each dimension contributes fairly.
