This visualization displays stacked bar chart data of general project funding items in 2018, broken down by institutional nature. It uses D3.js APIs including `d3.layout.stack`, `d3.scale.ordinal`, and `d3.svg.axis`. The chart colors segments by category, with an interactive legend that filters foreground bars on hover. Tooltips appear via `d3-tip`, showing item counts per segment and sub-category. Data comes from a CSV file with sales figures, rendered as animated SVG.
