public class EChartsTreemapChart extends EChartsChart<EChartsTreemapChart>
A treemap chart implementation for displaying hierarchical data as nested rectangles.

Treemap charts are useful for visualizing:

  • Disk space usage
  • Stock market sectors and performance
  • Organizational budget allocations
  • Hierarchical category distributions

Features include:

  • Multi-level hierarchical data
  • Interactive drill-down
  • Customizable colors per level
  • Breadcrumb navigation
  • Various layout algorithms (squarify, binary, etc.)

Example usage: 


 EChartsTreemapChart treemapChart = new EChartsTreemapChart();
 treemapChart.setSize(800, 500);

 // Create treemap series
 EChartsTreemapSeries series = treemapChart.createTreemapSeries("Disk Usage");

 // Add hierarchical data
 EChartsTreemapData root = EChartsTreemapChart.createData("Root", 100);
 root.addChild(EChartsTreemapChart.createData("Documents", 40));
 root.addChild(EChartsTreemapChart.createData("Pictures", 35));
 root.addChild(EChartsTreemapChart.createData("Videos", 25));
 series.addData(root);
