Fork of Animated Reusable D3 Scatter Plot
This animated scatter plot cycles through the numeric columns of the classic Iris dataset, changing the x-axis variable every three seconds while keeping sepal width on the y-axis. Using D3 v6, it leverages `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to render axes, and D3's `transition` with a one-second duration to animate both the movement of circles and the fading of axis titles. The visualization is drawn as an SVG, with the data fetched as CSV from a GitHub gist, and updates a reusable chart component via D3's join operation for enter, update, and exit states.
