Heatmaps and treemaps are powerful data visualization tools that offer specific advantages when examining large datasets. A heatmap colorizes data values in a matrix, allowing for intuitive observation of trends, patterns, and outliers over two dimensions, making it helpful for spatial data analysis and correlation assessment. Treemaps exhibit hierarchical data as nested rectangles, with size and color variations indicating distinct quantitative values, allowing for effective use of space and fast comparison of proportions and relationships within hierarchical structures. Together, these chart types provide significant tools for visualizing and interpreting complex data, improving decision-making processes by presenting underlying data insights in a clear and actionable manner.

Several jQuery chart controls support the Heat and Treemap chart types, including:

  • DevExtreme Chart (part of DevExtreme Complete by DevExpress) offers a jQuery treemap component that allows for the hierarchical representation of data in a compact format.
  • Highcharts Core by Highsoft is a powerful and versatile JavaScript charting library that works with jQuery and supports various chart types including treemaps/heatmaps.
  • Kendo UI for jQuery Chart (part of Kendo UI by Telerik) includes jQuery heatmap and treemap controls that emphasize responsive design and rich interactivity.
  • Ignite UI jQuery Chart (part of Infragistics Professional) offers a wide range of interactive JavaScript/HTML5 charts including heatmaps/treemaps.
