This stacked bar chart visualizes 2018 general project funding items by academic department and institution category (schools, research institutes, and others). Hovering over a data point displays a tooltip with the exact item count, while interacting with the color legend fades unrelated bars. The visualization uses D3.js for data binding, scales, axes, and SVG rendering, with the d3.legend and d3.tip libraries for the interactive legend and tooltips. Data originates from the provided CSV file, encoded through a stacked layout API and ordinal scale for the categorical y-axis.
