Heatmap Chart with Grouped Category Axis Example

This example shows a heatmap chart built with AG Charts, nesting one category inside another on a grouped category axis, so the grid carries two levels on a single axis and comparisons can be made within a group or across them. A four-stop colour scale maps the value, the axis emboldens its second level, and a tooltip renderer reports both category values for the hovered cell.
