Interactive Radar & Spider Chart Builder
The Radar Chart Creator (often called a spider chart, web graph, or polar chart) is a free online design utility that helps developers, designers, and analyst teams visualize multivariate data. By plotting metrics along multiple axes radiating from a central point, a radar chart makes it simple to compare skills, performance, or attributes across different categories at a glance.
This tool runs locally in your browser to protect your data privacy. No series names, variables, or numeric parameters are sent, stored, or processed on our servers.
When to Use a Radar Chart
- Skills & Competency Profiling:
- Visualize a developer’s skillset across different languages (e.g. JavaScript, Python, SQL, CSS, Devops) to identify gaps or balance.
- Product & Attribute Comparison:
- Compare two or more competitive products across several dimensions (e.g. Price, Ease of Use, Support, Features, Speed).
- Gaming & RPG Stat Visuals:
- Design classic character attribute graphs (e.g., Strength, Speed, Intellect, Stamina, Luck) for game design balancing.
How to Create and Export Your Graph
Step 1: Customize Variables (Axes)
Add the dimensions you want to evaluate. You need at least 3 variables to create a spider chart. Enter a name in the text box and click Add Axis. Click the close button (×) on any badge to delete it.
Step 2: Manage Data Series
You can plot multiple entities simultaneously to compare them. Click + Add Series to create a new comparison group. Give each series a unique name and pick a custom hex color from the color picker.
Step 3: Enter Numerical Values
Use the live data grid input table at the bottom of the editor panel. Change the values for each variable/series combination. The preview canvas on the right will update in real time.
Step 4: Preview and Download
- Click 👁️ Preview Output to inspect the full-resolution generated image in a clean preview window.
- Click Download PNG to save the graphic as a raster image.
- Click Download SVG to export the chart as a vector file, perfect for embedding in responsive websites or scaling in vector design tools like Figma and Illustrator.
Frequently Asked Questions (FAQ)
Is my private data sent to a server?
No. The entire radar rendering process takes place on the client side inside your browser using HTML5 Canvas and local SVG string compilers. No data grids or custom titles are uploaded to DwellixTools.
Can I change the shape of the grid lines?
Yes. Under Chart Settings, toggle the Grid Shape option:
- Polygonal: Standard concentric polygons connecting the axis ticks.
- Circular: Concentric circular guides, which are preferred for polar plots.
What is the maximum scale limit?
By default, the scale runs from 0 to 100. You can change the Maximum Scale Value field to any positive number (e.g., 5 or 10) to match your grading system.
How do I embed the vector graph in a website?
Download the SVG version. You can open the .svg file in any text editor, copy the <svg> code block, and paste it directly into your HTML, Astro, or React codebases for a pixel-perfect, scalable image.
