It is a circular statistical graphic where the size of each segment (petal) is proportional to the value it represents, allowing for easy comparison of data across categories. ### What data format is required? The tool requires a JSON array of objects, where each object contains at least a 'label' and a 'value' field. ### Can I use custom colors? Yes, select the 'Custom Colors' scheme and provide a JSON array of hex color codes to match your branding. ### Is the chart interactive? Yes, you can enable tooltips to show detailed information when hovering over specific segments of the chart. ### Can I show percentages instead of raw values? Yes, you can toggle the 'Show Percentages' option to display the relative proportion of each segment. ## Related tools - [Rating Star Chart](https://elysiatools.com/en/tools/rating-star-chart): Create beautiful star rating visualizations for products, services, and user feedback analysis with interactive animations - [Timeline Generator](https://elysiatools.com/en/tools/timeline-generator): Generate beautiful and interactive timelines from events data with various layouts and styles - [Data URI Generator](https://elysiatools.com/en/tools/data-uri-generator): Convert files into Data URIs (Base64 or percent-encoded) for inlining images, fonts, and assets directly into HTML, CSS, or Markdown - [Progress Ring Chart](https://elysiatools.com/en/tools/progress-ring-chart): Create beautiful circular progress indicators with animations, perfect for displaying percentages, completion rates, and progress metrics - [Radar Chart Generator](https://elysiatools.com/en/tools/radar-chart-generator): Generate customizable radar charts (spider charts) from data, perfect for multi-dimensional comparison and analysis - [Stream Graph Generator](https://elysiatools.com/en/tools/stream-graph-generator): Generate beautiful stream graphs for time series data with smooth flowing animations and baseline variations - [Waterfall Chart Generator](https://elysiatools.com/en/tools/waterfall-chart-generator): Create waterfall charts to visualize cumulative changes with positive/negative value distinction and subtotal display - [Word Cloud Generator](https://elysiatools.com/en/tools/word-cloud-generator): Generate beautiful word clouds from text with customizable fonts, colors, and sizes ## Samples - [Grafana Advanced Application Samples](https://elysiatools.com/en/samples/grafana-samples): Comprehensive Grafana samples covering advanced dashboard design, alerting configurations, data source integrations, and plugin development - [D3.js Data Visualization Samples](https://elysiatools.com/en/samples/d3js-data-visualization): Comprehensive D3.js data visualization examples including charts, maps, animations, and interactive visualizations - [QR Code Samples](https://elysiatools.com/en/samples/qrcode-samples): Sample QR code images for testing QR code reading and generation tools - [ELK Stack Log Analysis Samples](https://elysiatools.com/en/samples/elk-stack-samples): Comprehensive ELK Stack (Elasticsearch, Logstash, Kibana) samples for log aggregation, processing, and visualization in distributed systems ## Related content - [Chart and Diagram Generators](https://elysiatools.com/en/hubs/chart-diagram-generators): Generate bar, line, pie, donut, scatter, radar, Gantt, Sankey, heatmap, funnel, treemap, and dozens more charts and diagrams from your own data in one visualization hub. - [JSON Interchange and Format Translation Tools](https://elysiatools.com/en/hubs/json-convert): Compare JSON conversion tools for CSV, YAML, TOML, GraphQL, XML, Markdown, Excel, BSON, EDN, and related structured formats in one hub. - [JSON Inspection, Diff, and Transformation Tools](https://elysiatools.com/en/hubs/json-utility): Compare JSON formatting, diffing, path inspection, schema validation, merging, transformation, and export tools in one hub for API and data workflows. - [JSON Schema, Mock Data, and API Fixture Generators](https://elysiatools.com/en/hubs/json-generate): Curated tools for JSON schema generation, mock payload building, and API fixture preparation in one hub.
