Overview

The Sunburst Chart Generator allows you to visualize complex hierarchical data through an intuitive radial layout, making it easy to identify proportions and relationships across multiple levels of your dataset.

When to Use

  • •When you need to display hierarchical data structures with multiple levels of nesting.
  • •When you want to compare the relative sizes of categories and sub-categories in a circular format.
  • •When you need a space-efficient alternative to traditional tree maps for presentations or reports.

How It Works

  • •Input your hierarchical data in the required JSON format, ensuring each node contains a name and either children or a value.
  • •Customize the visual appearance by selecting a color scheme, adjusting the inner radius, and setting the maximum depth.
  • •Toggle display options like labels, values, and percentages to tailor the chart to your specific data storytelling needs.
  • •Generate the chart and export it as a high-quality visual for your project or document.

Use Cases

Visualizing organizational structures or departmental budget allocations.
Mapping website navigation paths or user journey flows.

Examples

1. Corporate Budget Breakdown

Financial Analyst
Background
The analyst needs to present the annual budget distribution across various departments and their respective sub-projects.
Problem
Traditional bar charts are too cluttered to show the multi-level hierarchy of the budget effectively.
How to Use
Paste the budget JSON structure into the 'Hierarchical Data' field and select the 'Business' color scheme for a professional look.
Example Config
colorScheme: 'business', showPercentages: true, showLabels: true
Outcome
A clear, circular chart that allows stakeholders to see the total budget and drill down into specific departmental spending at a glance.

2. Website Traffic Analysis

SEO Specialist
Background
The specialist wants to show how traffic flows from the homepage to various sub-directories and landing pages.
Problem
Standard analytics tables make it difficult to visualize the drop-off and distribution of traffic across the site hierarchy.
How to Use
Input the site structure data, set the 'Inner Radius' to 20% to create a donut-style sunburst, and enable 'Show Values'.
Example Config
innerRadiusPercent: 20, showValues: true, showPercentages: true
Outcome
A visually engaging sunburst chart that highlights the most popular paths and content clusters on the website.
