Responding to Resize

This example demonstrates a D3.js visualization that dynamically resizes an SVG graphic to match its container’s dimensions. The page’s CSS fixes the chart div to fill the viewport, and the `redraw` function reads `clientWidth` and `clientHeight` to update the SVG’s width and height attributes. It then draws two green, semi-transparent diagonal lines forming an X, whose endpoints are recalculated on every resize. The code uses the browser’s `resize` event listener to invoke `redraw`, alongside D3’s data join for efficient line updates.

This example demonstrates how a D3.js v5 SVG visualization can respond to browser resizing. The chart container fills the page using CSS, and the `redraw()` function extracts its `clientWidth` and `clientHeight` to set the SVG’s dimensions. It then draws a dynamic X shape—two green lines with 100-pixel stroke width—that always spans the full viewport. A `window` resize event listener triggers `redraw()` on every size change, ensuring the visualization stays responsive without recalculating scales. The rendering relies on SVG elements and direct attribute updates.

This example demonstrates how a D3.js visualization can respond dynamically to browser window resizing by redrawing an SVG element to match its container’s current dimensions. The code uses `clientWidth` and `clientHeight` to extract the CSS-computed size of the chart div, then updates the SVG’s `width` and `height` attributes accordingly. It renders two green diagonal lines forming an X, with a thick stroke and partial opacity, to visually confirm the resizing behavior. The `window.addEventListener('resize', ...)` triggers the `redraw` function on every viewport change.

This example demonstrates how a D3.js visualization can respond dynamically to browser resizing. A green X-shaped pair of lines fills the entire viewport, with the SVG’s width and height attributes continuously updated based on the container’s client dimensions. The code uses a CSS fixed-position div to define the chart area, then directly sets the SVG dimensions via `clientWidth` and `clientHeight` within a `redraw` function. A `window.addEventListener("resize", redraw)` triggers the update, while D3’s data join (`selectAll`, `enter`, `merge`) efficiently redraws the line elements with updated coordinates and stroke properties.

This example demonstrates how a visualization can dynamically respond to browser window resizing. The code uses D3 v5 to render an SVG cross composed of two green lines that span the full width and height of the chart container. A CSS rule fills the page with the container, and a `redraw` function extracts its `clientWidth` and `clientHeight` to update the SVG attributes and line coordinates. A window `resize` event listener triggers this redraw, ensuring the graphic continuously adapts to viewport changes.
