This line chart shows the closing prices and 7-day simple moving averages for three cryptocurrencies—AAVE, XMR, and LTC—selected via radio buttons. Users can switch between assets to compare price trends over time. The visualization uses d3.csv to load data, d3.scaleTime and d3.scaleLinear for axes, and d3.line to draw paths for both price and SMA series. The data originates from a Kaggle dataset on historical prime rates, though adapted for crypto here.
