This pie chart visualizes the distribution of video game genres based on user ratings below 5.0. The visualization loads CSV data from a GitHub Gist and renders it as a donut-style chart using D3.js. The code employs `d3.pie()` to compute arc segments, `d3.arc()` for both the outer path and inner label positioning, and `d3.scaleOrdinal()` with `d3.schemeCategory10` for color encoding. Each genre label is placed at the centroid of its corresponding arc using the `label.centroid()` transformation.
