This example demonstrates a responsive bar chart with axes that maintain consistent tick mark density across different screen sizes. The visualization uses D3.js to render the SVG elements, while a ResizeObserver watches the container and updates the chart’s width and height state accordingly. The axes automatically recalculate their tick counts based on the available space, ensuring readable labels whether viewed in a small panel or full-screen mode. The code structures reusable axis and label modules, highlighting a clean separation of concerns for building adaptive visualizations.
