This fork of a line chart visualizes the relationship between Maths and Science marks for a dataset. It renders a single red line path connecting data points, with a time-scaled X axis for Maths and a linear Y axis for Science, using d3.scaleTime, d3.scaleLinear, d3.axisBottom, d3.axisLeft, and d3.line. The SVG output is 960 by 500 pixels, with labeled axes and a title, using data loaded from a CSV file via d3.csv.
