A stylized area chart displays layered time-series data using a silhouette offset to show relative values across categories. The visualization uses D3 v2 with SVG rendering and cardinal interpolation to create smooth, overlapping curves in an orange color palette. Users can hover over any layer to highlight it while dimming others, with a tooltip revealing the specific category name and value at the cursor position. The chart loads data from an external CSV file and includes both left and right y-axes with a weekly time scale on the x-axis.
