This area chart displays cryptocurrency price trends over time, with the x-axis representing years and the y-axis showing values. The visualization uses D3.js v7 to load CSV data from a remote GitHub source, converts the data to numeric format, and renders an SVG area chart filled with steelblue. The code constructs linear scales for both axes, generates an area path using d3.area(), and adds axis labels for "Year" and "Value" through d3.axisBottom and d3.axisLeft.
