This area chart visualizes the average life expectancy across years, titled "Death By stroke," with data sourced from a CSV hosted on GitHub. It uses D3 v5 with an SVG rendering approach, employing `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and the `area` generator with `curveBasis` to create a smooth filled path. The chart includes axis labels, tick marks, and a title, all styled via an external CSS file.
