This example demonstrates interactive axes with crosshair guides that track the mouse cursor. As the pointer moves over the plot area, dashed lines extend from the cursor to the axes, accompanied by numeric value labels that display the current x and y coordinates. The visualization uses D3's `scaleLinear` for coordinate mapping and `axisBottom`/`axisLeft` for rendering ticks. Crosshair lines and value labels are dynamically joined to the SVG via the D3 `join` operation, updating on every mouse movement event.
