Implementing HeatMap

The HeatMap Chart component is a powerful visualization tool for displaying two-dimensional data where values are represented through color gradients or fixed colors. Perfect for analyzing patterns, correlations, and distributions in matrix data, time-series heatmaps, and any scenario requiring color-encoded data representation.

When to Use This Skill

• Data Matrix Visualization: Display 2D data arrays with color-coded cells
• Correlation Analysis: Visualize relationships between multiple variables
• Time-Series Heatmaps: Show patterns over time (e.g., hourly/daily activity)
• Category Comparison: Compare performance across categories and metrics
• Intensity Mapping: Display heatmaps with gradient colors representing value intensity
• Interactive Selection: Enable user selection of cells with tooltips and event handling
• Accessibility Requirements: Implement WCAG-compliant heatmaps with ARIA support
• Custom Styling: Apply themes, palettes, and custom rendering (SVG/Canvas)
• Bubble Heatmaps: Visualize data as bubbles with size and color encoding
• Large Datasets: Handle auto-switching between SVG and Canvas rendering modes
