This example demonstrates how a D3.js visualization can respond dynamically to browser window resizing. It shows a full-page SVG containing a large green X shape, where the X’s endpoints are recalculated to match the current viewport dimensions whenever the window is resized. The code uses `d3.select` to append an SVG element to a fixed-position chart container, then defines a `redraw` function that reads the container’s `clientWidth` and `clientHeight` properties to update the SVG’s `width` and `height` attributes. It binds the X’s line coordinates through D3’s data join pattern, and registers the `redraw` function as a listener for the browser’s `resize` event.

This example demonstrates how a D3.js v5 visualization can dynamically respond to browser resizing. The chart container fills the page via CSS, and a `redraw` function extracts the current `clientWidth` and `clientHeight` to set the SVG element’s dimensions. It then draws a large green X using two SVG `line` elements whose endpoints are computed from those dimensions. A `window` `resize` event listener triggers `redraw`, ensuring the X always spans the full viewport. The rendering uses pure SVG with D3’s data join pattern.

This example demonstrates how a D3.js visualization can respond dynamically to browser resizing. A full-screen SVG element displays a large green X composed of two diagonal lines, with the chart container styled to fill the viewport using fixed CSS positioning. The `redraw()` function extracts the container’s current dimensions via `clientWidth` and `clientHeight`, then updates the SVG’s width and height attributes and adjusts the line coordinates accordingly. A window `resize` event listener triggers a redraw on every size change, ensuring the graphic always fits the available space.

This example demonstrates how a D3.js visualization can respond dynamically to browser resizing. It shows a green X shape drawn with SVG lines that maintains its position relative to the viewport as the window changes dimensions. The code uses a `window.addEventListener("resize", redraw)` callback, which queries the container’s `clientWidth` and `clientHeight` properties to update the SVG’s `width` and `height` attributes. The `redraw()` function re-binds the line data and updates the `x1`, `y1`, `x2`, and `y2` attributes via `merge()`. The chart container is styled with fixed CSS positioning to fill the entire page.

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.

This example demonstrates how to keep a D3.js visualization responsive to browser window resizing. It shows a green X spanning an SVG element that always fills the viewport, with the chart’s dimensions extracted from the CSS-styled container using `clientWidth` and `clientHeight`. A `resize` event listener triggers the `redraw` function, which updates the SVG’s `width` and `height` attributes and repositions the two lines via data joins. The code uses D3 v5 and relies on SVG for rendering.

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 adapt to browser window resizing. A full-page SVG displays a green X composed of two thick lines that stretch to match the container’s current dimensions. The code uses a `redraw` function to read `clientWidth` and `clientHeight` from the chart’s `div`, then updates the SVG’s width and height attributes and the line coordinates via a data join. A native `window` `resize` event listener triggers a redraw whenever the viewport changes.

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.
