This scatter plot visualizes the relationship between study hours and exam scores for a group of students, using data from a CSV file. Each circle represents a student, positioned by study hours on the x-axis and exam score on the y-axis, with colors assigned via `d3.scaleOrdinal` based on student ID. The visualization uses D3.js v7 to render an SVG, drawing circles and axes with `d3.axisBottom` and `d3.axisLeft`, and labels for each axis.
