This area chart displays base experience values for the first 100 Pokémon from the PokeAPI, with the Pokémon index on the x-axis and base experience on the y-axis. The visualization uses D3.js v7 to fetch data via the PokeAPI, create linear scales, render axes with labels, and generate the area path using `d3.area()`. The SVG chart applies a steelblue fill to the area beneath the line, with clearly labeled axes for readability.
