This example demonstrates a data visualization with responsive axes that maintain consistent tick mark density as the viewport resizes. The chart displays a simple, abstract dataset within a gray inner rectangle, featuring labeled X and Y axes. The core behavior is achieved by using a ResizeObserver to track container dimensions, which then dynamically recalculates the number of axis ticks based on the available inner width and height. The implementation relies on D3.js functions like `scaleLinear`, `axisBottom`, `axisLeft`, and custom modules for axis and label rendering, ensuring the tick spacing remains visually uniform across different screen sizes.
