This visualization analyzes Pokémon type effectiveness through two linked views: a horizontal bar chart showing type counts and a matrix displaying damage multipliers between types. Hovering over a bar highlights the corresponding row in the effectiveness table, showing matchups against all other types. The bar chart uses `scaleLinear` and `scaleBand` for axes, while the matrix is rendered as an HTML table within a `foreignObject`. Data loading uses `csv()`, and interactivity relies on mouseover events that adjust rectangle opacity and table styling.
