Fork of Fork of Fork of Scatterplot for peng bird dataset
This example demonstrates two hover-activated dropdown menus built with a clean CSS-only reveal mechanism, listing static options. While the menus themselves have no linked data, the code includes a D3.js v6 event handler that logs clicked items and a separate, commented-out selection script using `d3.select` to track multi-select options with custom styling. The primary interactive behavior shown is the click logging, while the dropdown functionality relies on CSS `:hover` states. The page uses plain HTML, CSS, and the D3 library for event handling, and serves as a minimal template for adding dropdown interactions.
