This line chart visualizes the relationship between total marks and student counts using a simple SVG-based line graph. The chart employs D3.js v7 with linear scales for both axes, rendering the data as a steelblue line with labeled axes and grid-free styling. It loads CSV data from a GitHub gist containing US Airline Traffic information, though the axis labels indicate educational metrics. The visualization demonstrates d3.csv for data loading, d3.scaleLinear for coordinate mapping, d3.line for path generation, and d3.axisBottom/axisLeft for tick marks.
