This animated D3 scatter plot displays ridership data for Golden Gate Transit (GGT) and Marin Transit (MUNI), cycling through three column-based views—Operator, Date, and Ridership—every 3.5 seconds. The visualization uses D3 v7's `scaleLinear` for axes and `transition` for smooth 1-second animations, with circles entering at radius 0, updating positions with staggered delays, and axes transitioning simultaneously. Data is loaded via `d3.csv` from a raw Gist URL, rendered as SVG with custom Share Tech font styling, and the animation loop is driven by `setInterval`.
