This pie chart visualizes the top 10 YouTube channels by genre, with each slice sized according to channel count. The visualization uses D3 v5 APIs including `pie()`, `arc()`, and `scaleOrdinal()` with `schemeCategory10` for color encoding. Data is loaded from a CSV via `d3.csv` and rendered as SVG paths, with a legend showing each genre and its corresponding channel count. The code sorts the data descending before slicing the top 10 entries.
