This visualization displays a stacked bar chart of career-level data, showing the distribution of Standard, Double, and No awards across two career levels. The chart uses a custom color palette with red, blue, and green bars, and demonstrates custom axis configuration with tick labels removed from the bottom axis. The code is built on D3 v4, loading data from a CSV file and using the `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, `axisBottom`, and `stack` APIs to process and render the SVG output.
