This visualization integrates a treemap with a schematic cell diagram, showing the distribution of differentially expressed genes across cellular locations. The treemap uses d3.hierarchy to display hierarchical gene-level data, while the cell diagram is drawn with SVG paths representing cellular compartments like the plasma membrane and cytosol. The cell regions are colored using d3.scaleSequential with interpolateBlues and interpolateReds based on net differential expression values. A filterable table lists gene details, with d3 transitions animating row updates. The data is loaded from remote JSON and TSV files, and interactions include zooming and clicking to highlight selected locations.
