Responding to Resize

This example demonstrates a D3.js v5 visualization that dynamically resizes an SVG to match the browser window. The page uses a fixed-position container to fill the viewport, and a `redraw` function reads the container’s `clientWidth` and `clientHeight` to update the SVG’s dimensions. It draws an X composed of two green lines with 100-pixel stroke width and 0.5 opacity, using a data join with `selectAll`, `enter`, and `merge`. A `window` resize event listener triggers `redraw` each time the window size changes.

This example demonstrates a responsive SVG visualization that adapts to its container’s size. It uses CSS to make a chart div fill the viewport, then extracts the computed `clientWidth` and `clientHeight` in a `redraw` function to dynamically set the SVG’s width and height attributes. The code draws two green crossed lines, creating an X, with a thick semi-transparent stroke. A window `resize` event listener triggers `redraw` whenever the browser dimensions change, ensuring the visualization always matches the available space. The implementation relies on D3 v5’s `select` and data-join methods for updating the lines.

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 visualization can dynamically respond to browser window resizing. It uses the CSS `clientWidth` and `clientHeight` properties to extract the current container size and applies these dimensions to an SVG element via the `attr` method. Two diagonal lines are drawn across the SVG to visually confirm the correct sizing, with a resize event listener triggering a full redraw. The code relies on D3 v5’s selection and data join patterns to update the line coordinates.

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 a simple, responsive SVG visualization that adapts to the browser window's size. It draws two thick green lines forming an X across the entire viewport, illustrating how CSS-computed dimensions are used to redraw the graphic on window resizing. The D3 v5 code, using `d3.select`, extracts the container's `clientWidth` and `clientHeight` to update the SVG's `width` and `height` attributes, then repositions the line elements via the `merge` operation. A `window.addEventListener("resize")` handler triggers the `redraw` function whenever the window changes.

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.

This example demonstrates how a D3.js visualization can dynamically respond to browser resizing events. The chart container fills the viewport using CSS positioning, and a redraw function retrieves the computed `clientWidth` and `clientHeight` to update the SVG element’s dimensions. Two diagonal lines are drawn from corner to corner to visually confirm the current size. The code uses the `resize` window event listener and D3 v5’s `.selectAll`, `.merge`, and `.attr` methods, though the initial call to `redraw()` is commented out.
