This area chart displays monthly S&P 500 price data from January 2000 through March 2010, rendered as a brushed time series. The visualization shows price fluctuations over time in steel blue, with an interactive brushX selection tool below the main chart that allows users to zoom into specific date ranges. The example uses d3.v5 with SVG rendering, employing scaleTime, scaleLinear, axisBottom, axisLeft, brushX, and area functions to construct the focus and context views, with data loaded from a CSV file.
