This example demonstrates a responsive D3 v7 chart with customizable axes, including rotated tick labels on both the X and Y axes. It shows how to adjust tick density, outer ticks, tick sizes, and axis label offsets through the exported `axes` and `viz` functions. The visualization uses `d3.axisBottom` and `d3.axisLeft` with `scaleLinear` scales, and automatically resizes via a `ResizeObserver` that updates the chart dimensions. A gray inner rectangle highlights the plotting area, with separate modules handling axis rendering, labels, and resize observation.
