This visualization shows the sentiment distribution of tweets about Ukraine, displaying the percentage of tweets categorized as negative, positive, or neutral in a pie chart. The chart uses D3.js v7 with an SVG rendering approach, pulling data from a GitHub-hosted CSV file. The code employs `d3.pie()` and `d3.arc()` to generate the pie slices, `d3.scaleOrdinal` with a custom color scale for sentiment categories, and the d3-legend library to display the color legend. Percentages are shown on each slice using `d3.format(".1%")`.
