Small multiples show a single time series per stock symbol from the provided stocks.csv data, with each chart displaying the price trend and its colored area fill. Each panel uses its own y-domain scaled to that symbol’s maximum price, while the x-axis uses a shared time scale across all charts. The visualization is rendered as SVG using d3.v4, with d3.nest grouping data by symbol, d3.area and d3.line generating the shapes, and d3.scaleOrdinal assigning distinct colors per stock.
