Okay, I can help you create an animated Bitcoin price chart using HTML, CSS, and JavaScript with the Chart.js library. We'll fetch some initial historical data and then simulate updates.

This setup fetches the last 30 days of Bitcoin price data from the CoinGecko API to initialize the chart. Then, it simulates adding a new data point every 2 seconds with a slight random price variation, creating an animated effect. The chart automatically scrolls as new data is added (after reaching 60 points).
