A donut chart displays all CSS named colors, with each color represented by a wedge filled with its own RGB hex value. The chart reads from a CSV file of named colors, loading it asynchronously with `d3.csv`. Built with Vue's template syntax and `v-for` to iterate over arc data, it computes the pie layout using `d3.pie().value(1)` and renders paths with `d3.arc()`. A computed property displays the loaded dataset's size in kilobytes, row count, and column count.
