This example visualizes mortality rates across U.S. states as an annotated pie chart, with each slice labeled and accompanied by a legend showing state names and death counts. The visualization uses D3 v5 (d3.pie, d3.arc, d3.scaleOrdinal) to generate SVG paths and text elements, pulling data from a remote CSV file. It applies a custom color scale to distinguish slices and renders the chart centered on an SVG canvas with a static legend to the right.
