This pie chart displays the distribution of network protocols observed in a cyber attacks dataset, showing each protocol’s relative frequency as a slice with a color-coded legend and percentage labels. The visualization counts occurrences of the “Protocol” column from a remote CSV file, then uses d3.pie and d3.arc to generate the SVG arcs, with d3.scaleOrdinal and d3.schemeCategory10 assigning colors. A hand-built legend lists each protocol alongside its computed share of the total.
