This example demonstrates two labeled Cartesian axes positioned around a shaded inner region. The visualization uses D3's `scaleLinear` and `axisBottom`/`axisLeft` to render the axes, with custom `text` elements for the X and Y axis labels, offset via configurable parameters. Data is generated programmatically as a fixed linear scale from 0 to 100, and the gray inner rectangle highlights the plotting area defined by the margins.
