This dashboard compares AI platform usage across April 2023–March 2025 using six visualization types: bar charts, grouped bars, line charts, pie charts, scatter plots, and a treemap. Built with React and D3 v7, it renders SVG with animated transitions, interactive tooltips, and controls for filtering by platform type, sorting, limiting data, and highlighting selected platforms. The data, loaded from a CSV via d3.csv, shows visit counts and year-over-year changes for chatbots and search engines.
