This example presents an intraday Yahoo Finance chart that combines a decorated price series with a volume chart. The price panel shows the open price as a gradient-filled area, a blue line, and a red exponential moving average (EMA), all overlaid with gridlines using the d3fc library. The lower volume panel renders bars colored red or green based on whether the close price is above or below the open. The chart uses d3.csv to load the data, d3.time.format for axis labels, and d3.svg to render the SVG output.
