biojs-vis-heatmap-d3

biojs-vis-heatmap-d3 renders color-coded heatmaps from biological data matrices to visualize patterns such as gene expression, protein interactions, and metabolic pathway changes.

Key Features:

• Data visualization: Converts biological data matrices into color-coded heatmaps representing individual matrix values as colors.
• Interactive visualization (D3.js): Implements interactive graphics with D3.js enabling dynamic exploration, zooming, and cell-level detail inspection.
• Customizable color scales and thresholds: Supports color gradients with configurable scales and thresholds to represent data value ranges.
• BioJS integration: Integrates within the BioJS ecosystem for composition with other BioJS components.

Scientific Applications:

• Gene expression analysis: Visualizes gene expression matrices across samples or conditions to reveal upregulation and downregulation patterns.
• Protein interaction comparison: Illustrates strength and frequency of protein interactions across conditions using color-coded matrices.
• Metabolic pathway assessment: Displays changes in metabolic pathway–related measurements to aid identification of regulatory nodes.

Methodology:

Converts biological data matrices into visual heatmaps using color gradients with configurable scales and thresholds and implements interactivity via D3.js for dynamic exploration.
