This example demonstrates a visualization container with responsive axes that maintain consistent tick mark density as the window is resized. The code uses D3.js scales and axis components, including `scaleLinear`, `axisBottom`, and `axisLeft`, to render the chart. A `ResizeObserver` detects container dimension changes, and the tick count is recalculated based on the inner width and height divided by a fixed pixel density. The axes and their labels update dynamically to match the new size.
