This example demonstrates an SVG-based bar chart that dynamically responds to browser resizing. The visualization fills the entire viewport using CSS positioning, while a redraw function extracts the current width and height from the chart container and updates the SVG element’s dimensions accordingly. Two diagonal green lines are drawn to visually confirm the resizing behavior. The implementation uses D3 v5, with d3.select and SVG line elements, and listens for window resize events to trigger redrawing.
