This example visualizes the financing of general projects in 2018 by technical post, showing the number of Ph.D., Master, Bachelor, and other personnel across various academic departments. The stacked bar chart uses d3.layout.stack with an ordinal y-scale and a linear x-scale, while d3.legend provides a color legend for filtering layers. Tooltips are generated via d3-tip, and the SVG rendering includes highlight interactions that fade base bars and redraw foreground layers on hover. Data comes from a CSV file containing department, duty, and population counts.
