How to use: Select a market from the dropdown, choose a time period (Day, Week, Month, YTD, Year), and pick what the bubble size represents (market cap or price change). The chart updates automatically via WebSocket every 10–60 seconds.
Technology: Built with Flask (Python), D3.js for visualization, and Socket.IO for real-time data streaming.
Who it's for: Individual investors, traders, and finance enthusiasts who want a quick visual overview of market momentum and relative size of assets.
