# Multi-level Pie Chart Generator Create concentric multi-level pie charts with hierarchical relationships and interactive drill-down functionality > Canonical page: https://elysiatools.com/en/tools/multi-level-pie-chart-generator - **Category:** Data Visualization - **Keywords:** multi-level pie chart, concentric chart, hierarchical data, drill-down, sunburst chart, organizational chart ## Overview The Multi-level Pie Chart Generator allows you to visualize complex, hierarchical data through interactive, concentric circles. By transforming nested JSON structures into intuitive sunburst-style charts, this tool helps you identify patterns and proportions across multiple levels of data with ease. ## Inputs - **Chart Title** (text): Title that will be displayed above the chart - **Hierarchical Data** (textarea): Hierarchical data as nested JSON object with numeric values at leaf nodes - **Inner Radius** (number): Inner radius of the innermost circle in pixels - **Outer Radius** (number): Outer radius of the outermost circle in pixels - **Color Scheme** (select): Select color scheme - **Start Angle** (number): Starting angle in degrees (0-360) - **End Angle** (number): Ending angle in degrees (0-360) - **Maximum Depth** (number): Maximum number of levels to display - **Center Label** (text): Text to display in the center of the chart - **Stroke Width** (number): Width of borders between segments in pixels - **Show Labels** (checkbox): Display segment labels - **Show Values** (checkbox): Display segment values - **Show Percentages** (checkbox): Display percentage values - **Enable Drill Down** (checkbox): Enable interactive drill-down functionality - **Font Size** (number): Font size for labels and values - **Title Font Size** (number): Font size for the chart title - **Font Family** (text): Font family for text elements - **Chart Width** (number): Width of the chart in pixels - **Chart Height** (number): Height of the chart in pixels - **Background Color** (color): Background color of the chart - **Enable Animation** (checkbox): Animate the chart when it loads - **Animation Duration** (number): Animation duration in milliseconds ## When to use - When you need to visualize hierarchical data structures like organizational charts or product categories. - When you want to compare the relative proportions of sub-categories within a larger dataset. - When you require an interactive interface to drill down into specific data segments for deeper analysis. ## How it works - Input your hierarchical data as a nested JSON object, ensuring numeric values are assigned to the leaf nodes. - Customize the visual appearance by adjusting parameters like inner/outer radius, color schemes, and font settings. - Enable interactive features such as drill-down functionality and animations to enhance user engagement. - Generate and export your interactive chart as an HTML file for use in presentations or web reports. ## Use cases - Visualizing corporate budget allocations across departments and individual project teams. - Mapping website traffic sources, broken down by platform, channel, and specific landing pages. - Displaying product inventory hierarchies, from broad categories down to specific stock keeping units. ## Frequently asked questions ### What data format is required? The tool requires a nested JSON object where each level represents a hierarchy and the final leaf nodes contain the numeric values to be visualized. ### Can I change the colors of the chart? Yes, you can select from various pre-defined color schemes, including warm, cool, pastel, and vibrant palettes. ### What is the drill-down feature? The drill-down feature allows users to click on a specific segment of the chart to zoom in and focus exclusively on that branch of the data hierarchy. ### How many levels can I display? You can set the maximum depth of the chart, with support for up to 5 levels of hierarchy. ### Is the chart interactive? Yes, the generated chart supports interactive drill-down and optional animations to make data exploration more intuitive. ## Related tools - [Comparison Bar Chart Generator](https://elysiatools.com/en/tools/comparison-bar-chart): Generate back-to-back bar charts for positive and negative value comparison, perfect for contrasting data sets - [Donut Chart Generator](https://elysiatools.com/en/tools/donut-chart-generator): Generate customizable donut charts (ring charts) from data with various styling options, perfect for showing proportions with a central space - [Funnel Chart Generator](https://elysiatools.com/en/tools/funnel-chart-generator): Generate customizable funnel charts from data, perfect for showing conversion rates, sales pipelines, and process flows - [Gantt Chart Generator](https://elysiatools.com/en/tools/gantt-chart-generator): Create professional Gantt charts with task timelines, dependencies, progress tracking, and milestone markers - [Milestone Chart Generator](https://elysiatools.com/en/tools/milestone-chart): Generate project milestone charts with timeline nodes and key achievement points - [Pictograph Generator](https://elysiatools.com/en/tools/pictograph-generator): Create pictographs using icons/symbols to represent quantities with customizable icons, colors, and layouts - [Pyramid Chart Generator](https://elysiatools.com/en/tools/pyramid-chart-generator): Generate pyramid charts for hierarchical structure visualization, perfect for organization charts, hierarchy levels, and proportional data - [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 ## Samples - [QR Code Samples](https://elysiatools.com/en/samples/qrcode-samples): Sample QR code images for testing QR code reading and generation tools - [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 - [WebRTC Real-Time Communication Samples](https://elysiatools.com/en/samples/webrtc-samples): Comprehensive WebRTC samples for peer-to-peer audio/video communication, data channels, screen sharing, and signaling server implementation - [Distributed Tracing Samples](https://elysiatools.com/en/samples/distributed-tracing-samples): Comprehensive distributed tracing examples using Jaeger, OpenTelemetry, and other modern observability tools for microservices architecture ## 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 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. - [JSON to Typed Code Generators (TypeScript, Go, Rust, Kotlin, Java, C#)](https://elysiatools.com/en/hubs/json-to-typed-code-generators): Paste JSON and get ready-to-use types: TypeScript interfaces, Go structs, Rust structs with serde, Kotlin data classes, Java classes, C# classes, Zod schemas, and inferred JSON Schemas. - [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.
