# Radar Chart V0 Template: Skills Matrix & Comparison Playbook - Tool: V0 Templates - Last updated: July 2026 ## TL;DR The Radar Chart v0 template gives you a Recharts RadarChart with multiple data series, axis label customisation, a dataset toggle, a score tooltip, and an optional live score editor — all inside Next.js. Fork in 5 minutes, swap in your own axes and scores using the prompts below, and ship a polished skills matrix, performance review, or competitor comparison chart without touching SVG or Recharts config from scratch. ## Frequently asked questions ### Is the Radar Chart v0 template free to use? Yes. All v0.dev community templates are free to fork. Forking costs zero credits; AI chat prompts to customise the chart draw on your normal V0 credit balance. ### Can I use this template commercially? V0 community templates are published under an MIT-style license that permits commercial use without attribution. Always verify the exact license shown on the template's v0.dev community page before shipping a commercial product. ### Why does my fork crash or show a blank chart after deploying to Vercel? The most common cause is missing 'use client' on RadarChartCanvas.tsx. Recharts uses browser APIs (ResizeObserver, SVG measurement) that don't exist in Node.js. Add 'use client' to the top of the file or wrap the component in dynamic(() => import('./RadarChartCanvas'), { ssr: false }). The gotchas section above has the exact fix prompt. ### How do I add my own axis names and scores? Use prompt 1 from the Prompt Pack above. Paste it into the V0 chat with your category names and score arrays. V0 updates the RadarChartCanvas data, SubjectAxisLabels, and ComparisonLegend in one go. ### My axis labels are cut off on mobile — how do I fix this? Recharts places PolarAngleAxis labels at fixed positions around the SVG. On narrow screens they fall outside the viewBox. Wrap RadarChart in a Recharts ResponsiveContainer and add a custom tick renderer that reduces font size below 640px. Use the gotcha fix prompt above for the complete implementation. ### Can I save the edited scores so they survive a page refresh? Not out of the box — DataInputPanel edits live in useState and reset on refresh. Use prompt 5 (Supabase snapshots) to persist radar states to a database and generate a shareable URL for each saved configuration. ### Can RapidDev help build a production version of this radar chart? Yes. RapidDev connects the radar chart to real survey or evaluation data, adds team management, and can build PDF export for reports. Visit rapidevelopers.com to discuss your project. ### How do I show three or more series on the radar without them overlapping? Set fillOpacity to 0.2 on all Radar series and use high-contrast colours. Render the series with the largest polygon area first in the JSX so smaller ones appear on top. Prompt 3 in the Prompt Pack above walks through adding a third series with correct layering. --- Source: https://www.rapidevelopers.com/v0-template/radar-chart © RapidDev — https://www.rapidevelopers.com/v0-template/radar-chart
