Treemap Chart

A tree map chart is a graphical representation that shows hierarchical data in a tree-like structure, where each category is represented by a rectangle or square.

Configuration

Option

Provide the JSON content to generate the chart dynamically. Sample data is given blow.

{
  "data": [
    {
      "name": "nodeA",
      "value": 10,
      "children": [
        {
          "name": "nodeAa",
          "value": 4
        },
        {
          "name": "nodeAb",
          "value": 6
        }
      ]
    },
    {
      "name": "nodeB",
      "value": 20,
      "children": [
        {
          "name": "nodeBa",
          "value": 20,
          "children": [
            {
              "name": "nodeBa1",
              "value": 20
            }
          ]
        }
      ]
    }
  ]
}

The tree structure for the content will be like the parent -> children relationships. Each block will have the 'name' and 'value' elements, and the block can have a set of child elements with the same properties.

Title

Provide a short and descriptive title for the chart that clearly summarizes the data and information being presented. This title should be concise yet informative, helping the audience understand the content of the chart at a glance.

Tooltip

This tooltip pops up when the user moves the mouse over the block area of the chart. This is commonly used to provide some extra or important information to the user on the usage of the widget.

The tooltip will be immediately shown when the user's mouse hovers over the widget, and immediately hides when the user's mouse leaves. This information will be contextual, useful, and informative.
