This bar chart displays the hit point (HP) values of Generation-1 legendary Pokémon, with each bar’s length proportional to HP and Pokémon names listed along the y-axis. Using D3 v6, the code loads data from a CSV, filters for legendary Pokémon from generation 1, and converts HP strings to numbers. It employs `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft`/`axisBottom` to render the axes as SVG elements. The chart visually compares the relative health stats of these creatures.
