A responsive SVG chart demonstrates how D3.js v5 axes and labels adapt to window resizing. The visualization renders a rounded rectangle background with labeled X and Y axes, both using linear scales from 0 to 1. The `d3.axisBottom` and `d3.axisLeft` generators create ticks whose density adjusts based on the available inner width and height, with tick positioning recalculated on every resize event via a window listener, applying the `marginConvention` helper for layout.
