This example demonstrates how a visualization can respond to browser window resizing by redrawing an SVG to match its container’s updated dimensions. It shows a green X spanning the full width and height of the viewport, with thick, semi-transparent strokes. The code uses `d3.select` to create an SVG element and a `redraw()` function that reads `clientWidth` and `clientHeight` from the chart’s `<div>`, then sets the SVG’s `width` and `height` attributes accordingly. A `window.addEventListener("resize", redraw)` triggers the redraw on every resize event, while `selection.enter().merge()` updates the two `<line>` elements’ coordinates.

This example demonstrates how a D3.js SVG visualization can adapt to browser window resizing, drawing a green X composed of two thick lines that span the full width and height of the container. It shows the size extraction and redrawing process in action. The code uses a `redraw` function that reads the dynamic `clientWidth` and `clientHeight` properties of the chart’s div, then updates the SVG’s `width` and `height` attributes accordingly via D3 selections and merges. A native `window.addEventListener("resize", redraw)` triggers the redraw on every viewport change, while CSS fixed positioning ensures the container fills the page.

Responding to Resize

This example demonstrates how a visualization can respond to browser window resizing. It draws two green diagonal lines forming an X that always spans the full width and height of the chart container, which fills the entire page via CSS. The code uses `d3.select` to append an SVG element, then extracts the container’s `clientWidth` and `clientHeight` inside a `redraw` function to dynamically set the SVG’s width and height attributes. A `window.addEventListener` for the `resize` event triggers `redraw`, updating the line coordinates using D3’s data join pattern.

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 full-page SVG visualization that responds to browser resizing by redrawing a large green X spanning the chart’s diagonal corners. The code uses a fixed-position div container with CSS to compute available space, then extracts its `clientWidth` and `clientHeight` inside a `redraw()` function. That function updates the SVG’s `width` and `height` attributes and binds two line data points to draw the X. A `window.addEventListener("resize", redraw)` triggers the redraw on every window size change, while d3.v5 manages SVG element selection and data joins.

This example demonstrates how a visualization can automatically respond to changes in the browser window size. It draws a green X spanning the full width and height of the viewport, with thick, semi-transparent strokes. The code uses CSS to make a chart container fill the screen, then relies on the `resize` event listener to trigger a redraw. Within the `redraw` function, D3 v5 selects the container and sets the SVG’s `width` and `height` attributes based on `clientWidth` and `clientHeight`, using a data-driven approach to update the lines’ coordinates.

This example demonstrates how a D3 v5 SVG visualization can dynamically respond to browser window resizing. It draws a large green X spanning the full viewport, with the chart container filling the page via fixed CSS positioning. The `redraw` function reads the container’s `clientWidth` and `clientHeight` to update the SVG’s width and height attributes, then repositions two `<line>` elements using a data join. A `window` resize event listener triggers `redraw` on every size change, ensuring the graphic always matches the available space.

Responding to Resize

This example demonstrates a D3.js visualization that automatically redraws itself to match the browser window’s current dimensions. It uses CSS to make a chart container fill the viewport, then reads the container’s `clientWidth` and `clientHeight` properties to size an SVG element accordingly. The visualization draws two thick, semi-transparent green lines forming an X, with coordinates recomputed on every window resize event via a `redraw` function. The code relies on the D3 v5 selection API, `d3.select`, and the `selectAll`/`enter`/`merge` methods to update the SVG lines.

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.
