This interactive visualization presents multiple coordinated views of Titanic passenger data, including gender and survival pie charts alongside age and fare histograms. Users can filter by passenger class via dropdown, while clicking pie chart slices triggers linked selections across all views. The code uses D3.js with `d3.pie`, `d3.arc`, `d3.histogram`, and `transition.attrTween` for animated updates, rendered as SVG. Data originates from the Titanic passenger manifest, though the README references a different population dataset without visible integration.
