This example shows how a D3 visualization can dynamically size itself to fill the page at load time, using an SVG element that matches the dimensions of its container. The code reads the container’s width and height via `clientWidth` and `clientHeight`, then appends an SVG with those exact dimensions. To verify the sizing, it draws two diagonal lines forming an X across the full area, using D3’s data binding and selection methods. The rendering relies on the SVG `line` element and CSS positioning to stretch the container. The visualization does not respond to window resizing after initial load.

AI-generated description

This example shows how to make a D3 visualization that fills up the size of the page at the time it is loaded. This is necessary when, for example, you want to be able to load your visualization into an iFrame that could be any size. This example was created to address this question on the D3 Google Group: Any advice for setting width in iframes with D3?.

Here's a variant that responds to resize.

Dynamic Size Example

This example demonstrates a D3 v4 visualization that dynamically resizes its content to match the browser window. It shows how to read the CSS-computed dimensions of a container div and apply them to set an SVG element’s width and height attributes. The rendering uses an SVG text element that updates its font size proportionally to the container’s width. The code listens for window resize events and calls a redraw function, which also uses D3’s data join pattern to update the text position and size.

Dynamic Size Example

This example shows how a D3 v4 visualization can dynamically fill the browser window and automatically redraw when the viewport resizes. It uses a fixed-position CSS container to define the available space, then reads `clientWidth` and `clientHeight` to set the SVG dimensions on each resize. The code draws two diagonal lines forming an X, with stroke opacity and width, to visually confirm the resizing works. A `window.addEventListener("resize", redraw)` triggers the redraw, while the initial call to `redraw()` handles the first render. The example uses plain SVG with D3’s selection and merge methods to update line attributes.

Dynamic Size Example

This example demonstrates a responsive SVG visualization that adapts to the browser window’s size. It uses D3 v4 to generate an SVG element whose width and height are dynamically recalculated via `clientWidth` and `clientHeight`, then draws two crossed lines to visually confirm the dimensions. The redraw function is triggered once on initialization and again whenever the window resizes, using `d3.select` and SVG line attributes to update the graphic in real time.

Responding to Resize

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.

Responding to Resize

This example demonstrates how a D3.js visualization can automatically adapt to its container size. A green X-shaped set of lines is drawn inside an SVG, and the entire graphic redraws whenever the browser window is resized. The code uses a fixed-position `#chart` div that fills the page, with `clientWidth` and `clientHeight` extracting the computed dimensions. Those values then set the SVG’s `width` and `height` attributes, and the lines are repositioned via a `redraw` function wired to the window’s `resize` event. The rendering uses SVG elements and D3’s data join pattern.

Responding to Resize

This example demonstrates how a D3.js visualization can dynamically adjust to fit its container. It draws a large green X composed of two diagonal lines that stretch from corner to corner, with the SVG element’s width and height updated to match the chart div’s client dimensions. The code uses `d3.select` and `selection.attr` to resize the SVG, and a `window.addEventListener("resize", redraw)` function to trigger the redraw. The rendering approach is SVG, with the chart container styled via CSS to fill the entire viewport.

Dynamic Size Example

This example demonstrates a dynamic, resizable visualization using the d3-boxes library, which computes nested rectangular layouts. When the browser window is resized, the `redraw` function recalculates the layout based on the new `clientWidth` and `clientHeight`, and updates an SVG graphic. The layout defines a vertical arrangement of boxes, including a horizontal sub-group whose size weight is doubled, and box "A" is given a size weight of 2. Each box is drawn with a colored rectangle, an X-shaped pair of lines, and a centered text label, all managed through D3's selection and merge APIs.
