This fork of a D3.js scatter plot animates through three pairings of nutritional data from a CSV file of menu items: carbohydrates versus protein, carbohydrates versus total fat, and protein versus total fat. The code uses D3 modules such as `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render axes and circles with an SVG. A `setInterval` callback updates the x and y value mappings every two seconds, changing the chart’s title accordingly. The visualization employs a custom `scatterPlot` function and D3’s `selectAll` and `join` for efficient updates.
