This interactive donut chart displays the proportion of three project statuses—Not started, Started but not completed, and Completed—using a color-coded SVG pie layout. Hovering over a slice highlights it and reveals a tooltip showing the exact percentage of that status. The visualization uses d3.pie and d3.arc to generate the donut geometry, with d3.scaleOrdinal mapping status names to colors. Data is loaded from a CSV file, and mouseover events update the tooltip’s position and computed percentage.
