This visualization demonstrates how to add clear, customized labels to the X and Y axes of a D3 chart. The code builds a simple scatterplot with a gray inner rectangle and axes rendered using D3's `scaleLinear`, `axisBottom`, and `axisLeft` functions. Text elements for the axis labels are positioned with computed offsets and rotations using `selectAll` and `.join`. Everything is composed modularly across separate files like `xAxisLabel.js` and `yAxisLabel.js`, with default styling applied via sans-serif font attributes.
