An interactive bar chart compares total visits for AI platforms across chatbots and search engines for 2024-2025. Users can filter by platform type, sort by total visits or year-over-year change, and toggle to show previous year indicators. Built with React and D3 v7 (including `scaleBand`, `scaleLinear`, and `scaleOrdinal`), it renders as animated SVG bars with hover tooltips and legend-based filtering, with data loaded from a CSV file.
