Github API Visualisation
This bar chart visualizes mutual following counts among GitHub users, ranking each contributor by the number of mutual connections they share. The data is loaded from a CSV file, with counts parsed as numbers and rendered as horizontal bars. Using D3 v5, the visualization employs `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisBottom` and `axisLeft` for tick marks. The SVG output styles bars in steelblue, with axes and labels generated programmatically from the data.
