A responsive visualization container uses a ResizeObserver to track the container’s dimensions and updates the state with the new width and height. The d3-selected SVG element re-renders an inner rectangle on each resize, with its fill, margins, and size defined by the viz function. This example demonstrates a pattern for making D3 visualizations adapt to their parent element’s size changes, using the ResizeObserver API and D3’s join method to manage the SVG and rectangle elements dynamically.

This example demonstrates a responsive SVG visualization where a gray rectangle remains centered within the container as its dimensions adjust dynamically. The code uses a `ResizeObserver` to continuously update the width and height in the component state, and D3’s `select` and `join` methods to efficiently render the SVG and rectangle. The inner rectangle's size is calculated from the container's current dimensions minus fixed margins, ensuring it always fits within the available space.

This example demonstrates a responsive SVG visualization that fills the entire browser window and redraws its content whenever the viewport size changes. The page uses CSS to stretch a chart container to full screen, then d3.js extracts the container’s clientWidth and clientHeight on each resize event to update the SVG’s width and height attributes. Two diagonal lines form a green X marker whose endpoints adjust to the current dimensions, showcasing how to bind data containing the new coordinates and re-render with a selection merge. The code relies on d3.select, selection.attr, and window.addEventListener for the resize handling.

This example demonstrates a simple responsive chart that dynamically adjusts an SVG to fill the browser viewport. It first extracts the client width and height from its container, then sets the SVG’s `width` and `height` attributes accordingly, and redraws two green diagonal lines to verify the resizing behavior. The visualization uses D3.js v5 to create and update the SVG elements, leveraging a listener for the window’s `resize` event to trigger the redraw. The code relies on the `d3.select` API to bind the chart container and `attr` to update the SVG dimensions.

This example demonstrates a responsive SVG visualization that fills the browser window and redraws its content whenever the viewport size changes. It uses a CSS-positioned chart container to extract the computed client dimensions, then applies those values to set the SVG’s width and height attributes. The visualization draws two thick green diagonal lines forming an X, with the line coordinates recalculated on each resize event. The code leverages d3.js version 5 to select the container, append the SVG, and bind data to the line elements using the enter-merge pattern.

This example demonstrates how an SVG visualization can dynamically adapt to the size of its container using CSS and the browser’s resize event. The chart fills the entire viewport via fixed positioning, and a green X composed of two thick lines is drawn from corner to corner to visually confirm that the dimensions are correct. The code uses D3 v5 to select the container, append an SVG element, bind data to line elements, and update their coordinates. On every window resize, the clientWidth and clientHeight properties are read and applied to the SVG’s width and height attributes, triggering a redraw.

This example demonstrates a full-page SVG that dynamically resizes to match its container. It uses D3 v5 to select the chart div and append an SVG element, then defines a redraw function which extracts the container’s CSS-computed `clientWidth` and `clientHeight` to set the SVG’s attributes. A green diagonal cross is drawn with `selectAll` and data-bound `line` elements, merging enter and update selections. The function runs initially and listens for the browser `window` `resize` event, redrawing the graphic to fill the viewport.

This example demonstrates how a D3.js visualization can automatically resize its SVG output to match the browser window’s dimensions. The code uses CSS to make a container div fill the viewport, then reads `clientWidth` and `clientHeight` to set the SVG’s width and height attributes. It draws an X shape using two green lines with heavy stroke width and opacity, showing the current size. The `redraw` function reapplies these dimensions whenever the window is resized by listening to the `resize` event.
