Treemap Chart Node

The Treemap Chart Node visualizes hierarchical data using nested rectangles, where each rectangle's size and color represent specific attributes of the data.

Overview​

This node requires the user to select a category column (hierarchical levels), a size column, and optionally a color column. Each rectangle represents a category, and its size corresponds to the value.

Key Features​

  • Hierarchical visualization: Display nested categories.
  • Size and color encoding: Represent multiple dimensions of data.
  • Interactive exploration: Drill down into categories.
  • Dashboard ready: Integrates seamlessly with dashboards.

Required Data​

  • categoryColumn: The hierarchical category column.
  • sizeColumn: The column determining the size of rectangles.
  • colorColumn (optional): The column determining the color of rectangles.

How it works​

  1. Add the Treemap Chart Node to your workflow.
  2. Connect your dataset.
  3. Select the category, size, and optional color columns.
  4. Configure display options as needed.
  5. The node renders a treemap chart.

Use Cases​

  • Sales breakdown: Visualize sales by product categories and subcategories, with size representing revenue and color indicating profit margin.
  • Population distribution: Display population by regions and subregions, with size representing population count and color indicating growth rate.
  • Resource allocation: Analyze resource usage across departments, with size representing allocation and color indicating efficiency.
  • Market share analysis: Compare market share across companies and sectors, with size representing market share percentage and color indicating growth trends.
  • Budget visualization: Track budget allocation across projects, with size representing budget amount and color indicating spending status.

Benefits​

  • Intuitive representation of hierarchical data.
  • Multi-dimensional analysis with size and color encoding.
  • Handles large datasets efficiently.
