Create custom radar charts online. Easily visualize and compare multi-dimensional data with our free spider chart maker.
Supports comma, semicolon, or tab delimited data. The first cell of the first row is the dimension name, and the rest are series names. A minimum of 3 dimensions is required.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
A radar chart, also called a spider chart, places each dimension on an axis radiating from a center. Each data series gets a value on every axis; connecting those values forms a profile. The chart is a visual display of the numbers you provide. It does not calculate an overall score, decide which profile is best, or rank the series.
Enter a simple table with a header row: the first column names the dimensions and each following column names a data series. Use at least three dimension rows and at least one value column. For example, a header such as Metric,Team A,Team B can be followed by rows for Speed,8,6, Quality,7,9, and Support,6,8. Values should be numeric and on scales that make sense to compare.
Each spoke corresponds to one row label, and distance from the center represents the value on that spoke. Overlaying series can help show where profiles differ. The filled polygon is a visual aid, not an extra measurement: its area is not an overall score. CDC guidance recommends using a common scale for comparable indicators and warns that many axes or mismatched scales can make a radar chart difficult to interpret. Read CDC guidance on radar charts.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Put dimension labels in the first column and series names across the header. Add at least three dimension rows. The editor accepts comma-, semicolon-, or tab-separated rows; use a consistent delimiter and avoid extra delimiter characters in labels.
Provide a number for each series at each dimension. Blank or nonnumeric cells are interpreted as zero, which can create an unintended inward point, so fill every value deliberately.
Add a chart title if useful. Choose a polygon or circular grid, set a positive maximum value when you need a fixed scale, and adjust the grid, legend, point markers, fill opacity, and series colors to improve readability.
Check that labels map to the intended spokes and that every series uses the same interpretation of the scale. Download a PNG for a raster image or an SVG for scalable vector use.
Use cases
See how the tool fits into real work and everyday tasks.
Plot ratings for a small group across shared skill dimensions. Use the same rating scale for each person and label how ratings were collected; the shape alone does not explain the reason for a score.
Compare a few products on consistently scored attributes. Keep the scoring direction consistent so that a longer spoke has the same meaning on every dimension.
Show a learner’s current profile across related topics or compare snapshots over time. Keep axis order and scale fixed when comparing charts so the visual change is meaningful.
Q&A
Find concise answers to common questions and confusing cases.
Yes, if it is a simple rectangular table with one header row, labels in the first column, and numeric values in the remaining columns. Tab-separated clipboard data is accepted alongside comma- and semicolon-separated rows.
Blank or nonnumeric value cells are treated as zero. Enter an explicit numeric value in every series cell and check the row and column alignment.
No. Area is only part of the drawing; the tool does not calculate a composite score or ranking. Compare the spoke values and use a separate, documented scoring method if an overall result is required.
Notes
