This visualization displays a color palette as a grid of interactive circles, each filled with a specific RGB hex value from a CSV file and labeled with its corresponding keyword. Hovering over any circle scales it up slightly to highlight the selection. The page uses D3.js v7's `d3.csv` to load and bind the remote data, then selects and styles DOM elements to render the circles. It also fetches the CSV file’s size via `fetch` with a HEAD request to report data length, along with row and column counts.
