This area chart displays the average life expectancy of males over a series of years, using a smooth, filled curve rendered as an orange SVG path. The visualization reads data from a CSV file hosted on a GitHub gist, processing the year as a date and the expectancy as a numeric value. Built with D3 v5, it employs `scaleTime` and `scaleLinear` for axes, `axisBottom` and `axisLeft` for ticks, and `area` with `curveBasis` to generate the smoothed area shape, alongside custom axis labels and a title.
