This visualization shows the distribution of low-income reading scores across U.S. states using a pie chart, with each slice colored and a corresponding legend listing state names and values. The data is loaded from a CSV file via D3’s `csv` method. The chart is rendered in SVG using `d3.pie`, `d3.arc`, and `scaleOrdinal` for coloring, while text labels are positioned with `arc.centroid`. The legend is built with appended rectangles and text elements.
