This example displays an area chart of the top 10 companies by market capitalization, using a light blue filled path to visualize values in billions. The visualization loads CSV data from a GitHub gist and renders it as SVG, drawing axes with D3's `scaleBand`, `scaleLinear`, `axisBottom`, `axisLeft`, and generating the area shape with the `area` generator. The code imports these modules via ES6 `import` statements from D3 v5, demonstrating local module usage and data parsing through a custom `parseRow` function.
