This stacked bar chart visualizes general project funding items across academic departments, categorized by institution type (schools, research institutes, and others). The visualization uses D3.js with a nested data structure and the `d3.layout.stack` API to create layered bars, showing funding distribution by department and category. Hovering over the color legend highlights specific institution categories, while a tooltip using `d3-tip` displays detailed values. The chart includes animated transitions and a custom legend via `d3-legend`, with the underlying data sourced from CSV files.
