This reusable scatter plot visualizes the relationship between study hours and exam scores using a green circular mark for each data point. Built with D3 v7, the visualization implements a functional chart factory pattern with configurable accessor functions for x and y values, margins, dimensions, and point radius. The chart renders SVG axes via `d3.axisBottom` and `d3.axisLeft`, with linear scales computed using `d3.scaleLinear` and `d3.extent` on the loaded CSV dataset. The modular design allows the plot to be easily reused with different datasets.
