# Chord Diagram Generator Generate interactive chord diagrams for visualizing bidirectional flows and relationships between entities > Canonical page: https://elysiatools.com/en/tools/chord-diagram-generator - **Category:** Data Visualization - **Keywords:** chord, diagram, relationship, flow, circular, network, visualization ## Overview The Chord Diagram Generator creates interactive, circular visualizations that effectively display bidirectional flows and complex relationships between multiple entities. ## Inputs - **Connection Data** (textarea): Array of connections with source, target, and value fields - **Chart Title** (text): Title displayed above the chart - **Sort Order** (select): Select sort order - **Color Scheme** (select): Select colors - **Background Color** (color): Chart background color - **Outer Radius** (number): Outer circle radius in pixels - **Inner Radius** (number): Inner circle radius in pixels - **Chord Opacity** (number): Chord transparency (0-1) - **Arc Padding** (number): Space between arcs (0-0.1) - **Show Labels** (checkbox): Display entity names - **Show Values** (checkbox): Display total flow values - **Show Legend** (checkbox): Display color legend - **Show Statistics** (checkbox): Display flow statistics - **Enable Animation** (checkbox): Animate on load - **Animation Duration (ms)** (number): Animation time in milliseconds ## When to use - When you need to visualize the movement or exchange of data between different groups. - When comparing the strength of relationships or connections across a network. - When presenting multi-directional flow data in a compact, circular layout. ## How it works - Input your connection data as a JSON array specifying the source, target, and value for each relationship. - Customize the visual appearance by adjusting color schemes, opacity, and arc padding. - Toggle display options like labels, statistics, and legends to refine the chart's clarity. - Generate the interactive diagram and use the built-in animation settings to bring your data to life. ## Use cases - Visualizing migration patterns between different cities or countries. - Mapping trade volume or financial transactions between global markets. - Analyzing user navigation paths or traffic flow between sections of a website. ## Frequently asked questions ### What format does the connection data require? The tool requires a JSON array of objects, where each object contains 'source', 'target', and 'value' fields. ### Can I change the order of the entities in the circle? Yes, you can select from various sort orders including alphabetical, original, or by value (high to low/low to high). ### Is the generated diagram interactive? Yes, the generated chord diagram is interactive, allowing users to hover over arcs and chords to see specific flow details. ### Can I customize the colors of the diagram? Yes, you can choose from several predefined color schemes like warm, cool, pastel, or vibrant to match your presentation needs. ### What is the purpose of the 'Chord Opacity' setting? Chord opacity controls the transparency of the connections, helping to reduce visual clutter when many flows overlap. ## Related tools - [Box Plot Generator](https://elysiatools.com/en/tools/box-plot-generator): Generate box plots for statistical distribution analysis with quartiles, whiskers, and outliers - [Barcode Batch Generator](https://elysiatools.com/en/tools/barcode-batch-generator): Batch generate Code 128, EAN-13, UPC-A, ITF-14, QR Code, and Data Matrix outputs from CSV or multiline text - [Range Chart Generator](https://elysiatools.com/en/tools/range-chart-generator): Create range charts to visualize min-max value ranges with median markers and outlier detection - [Slug Generator](https://elysiatools.com/en/tools/slug-generator): Generate clean URL slugs from any text, with built-in Chinese-to-Pinyin conversion.
