Free spider chart tool

Free Radar Chart Maker

A radar chart (spider chart) plots three or more criteria on spokes from a shared center, so each product, competitor, or release becomes a shape you can compare at a glance. Enter or paste scores below to make a radar chart with an honest scale, then export it as SVG or PNG, all privately in your browser.

Series are compared criterion by criterion. We never rank by polygon area, because area depends on axis order and scale.

How to make a radar chart in 5 steps

  1. Step 1

    Choose a template or paste data

    Start from a customer feedback scorecard, feature comparison, release before/after, skills matrix, or positioning template, or paste a CSV with criteria in the first column and series in the header row.

  2. Step 2

    Set the scale

    Keep one shared scale, either automatic or an explicit min and max such as 1-5 or 0-100. Normalize each axis only when criteria use different units.

  3. Step 3

    Mark lower-is-better axes

    Tick lower is better for criteria such as price, effort, or bug count. The axis is inverted and labelled so that outward always means better.

  4. Step 4

    Style and compare

    Pick accessible series colors, gridline rings, fill opacity, and value labels. Hover or focus a point for its original value, and toggle series in the legend.

  5. Step 5

    Export or share

    Download SVG or a 2x PNG with a white or transparent background, copy the data as CSV, print, or copy a share link that carries the data in the URL.

Using radar charts for product feedback

Compare competitor scorecards. Average your customers' 1-5 ratings for usability, reliability, support, and value, then overlay competitors from reviews or win/loss interviews to see where you lead and trail.

Check releases before and after. Plot satisfaction by area before and after a launch on the same 0-100 scale. Areas that move inward deserve a closer look, even if the overall average went up.

Summarize survey categories. Turn category scores from a feedback survey into one profile per segment, such as free vs paid users. Keep the scale shared and compare spoke by spoke, never by polygon area.

Radar chart questions

What is a radar chart?

A radar chart, also called a spider chart or spider web chart, plots three or more variables on axes that start from the same center point. Each series becomes a polygon, so you can compare profiles such as product scores across usability, reliability, and support at a glance.

When should you use a radar chart vs a bar chart?

Use a radar chart to compare the overall profile of a few items (one to six) across the same 3 to 12 criteria on a shared scale, such as competitor scorecards. Use a bar chart when you need precise comparisons of values, many categories, or many items, because bar lengths are easier to read than distances on a circle.

How do you read a spider chart?

Each spoke is one criterion. The center is the scale minimum and the outer ring is the maximum, so points farther out score higher. Compare series spoke by spoke: where one polygon sits outside another, that series scores better on that criterion. Check the scale and any inverted, lower-is-better axes first.

Why can radar charts be misleading?

Polygon area grows with the square of the values and changes when you reorder the axes, so a bigger shape is not a valid overall score. Mixed or per-axis scales also change the shape. Keep one shared scale when you can, label inverted axes, and compare criterion by criterion or with averages instead of area.

How many variables can a radar chart show?

A radar chart needs at least 3 variables and stays readable up to about 10 to 12. This tool allows 3 to 12 criteria and up to 6 series; beyond that, labels crowd and overlapping polygons hide each other, so a bar chart or table works better.
