This example demonstrates responsive chart axes that maintain consistent tick mark density as the visualization resizes. A grey inner rectangle and labeled axes adapt their tick counts based on the available width and height, ensuring readability across different screen dimensions. The code uses `ResizeObserver` to track container size, then dynamically calculates tick numbers from the scale’s range. It leverages D3.js methods like `axisBottom`, `axisLeft`, and `scaleLinear` within a modular structure of separate axis and label components. The visualization also includes full-screen mode for interactive resizing.
