This example shows a reusable scatter plot built with D3 v7, mapping the `age` column to the x-axis and the `rating` column to the y-axis for a small CSV dataset of 12 individuals. The chart displays points as blue circles with opacity, along with labeled axes and a title. The code implements a `scatterChart()` factory function that uses D3's `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` APIs to construct the visualization. It leverages the `.join` pattern to create SVG elements and the `d3.csv` method with `autoType` to load and parse the data from `rithvik_ice5_data.csv`.
