This example presents a reusable scatter plot that visualizes data read from a Google Sheets document via the Google Visualization API. The chart maps two selected spreadsheet columns to x and y positions using D3’s `scaleLinear`, rendering circles with an SVG `join` pattern. Axes are drawn with `axisLeft` and `axisBottom`. The implementation follows a reusable chart pattern, allowing configuration of data, margins, radius, and value accessors.
