This visualization presents the survival distribution of Titanic passengers as a pie chart, using D3.js to render each passenger category as a colored slice. It shows the proportion of survivors versus casualties with interactive hover tooltips that display the count and percentage for each group, alongside a legend summarizing total counts. The chart uses d3.pie and d3.arc to generate the SVG slices, with d3.scaleOrdinal and schemeCategory10 for coloring. Data comes from a CSV dataset fetched from a GitHub gist, filtered by the "Survived" field.
