This example demonstrates two approaches to drawing a circle with D3, resulting in side-by-side red and blue circles. One circle is created directly in static SVG markup within the HTML, while the other is generated dynamically using D3’s selection and append methods, chaining `attr` calls to set the `cx`, `cy`, and `r` properties and `style` to fill the shape. The code uses `d3.select` and `d3.append` from the D3 v5 library to construct the SVG element and its circle child, showcasing basic programmatic SVG creation.

D3: Drawing SVGs

This example demonstrates how to create basic SVG shapes with D3.js by rendering five circles of increasing radius. The code uses D3’s data join pattern, calling `selectAll`, `data`, `enter`, and `append` to bind an array of five numbers to circle elements. Each circle’s x-position is calculated from its index, its radius from the bound data value, and its fill, stroke, and stroke-width are set accordingly. The static SVG is 500 pixels wide and 50 pixels tall, with all circles vertically centered.

Presentation SVG

This example demonstrates how to style and manipulate basic SVG circle elements using D3.js selections. The static HTML page contains three circles positioned horizontally, and the JavaScript code first applies a uniform red fill to all circles, then conditionally recolors them based on their index—alternating between red and blue. The visualization relies on D3's `selectAll` method to query SVG elements and the `style` method to set CSS properties. The circles are rendered as static SVG shapes without any data binding or interaction, showcasing simple DOM manipulation with D3 v7.

Drawing SVG rect with D3

This example demonstrates two ways to render a blue SVG rectangle: one statically defined directly in HTML markup, and another generated dynamically using D3’s selection and data-join methods. The code uses `d3.select` to append an `svg` element to the body, then chains an `append('rect')` call to set its width and height attributes via `.attr()` and its fill color via `.style()`. A hand-written `<rect>` element appears above as a visual comparison, while the D3-generated rectangle is rendered below, with both sharing the same dimensions and color.

Circles with D3

This example uses D3 to draw a static set of colorful circles on a white background. The `select` function creates an SVG container, and the code binds an array of data objects to `circle` elements, setting each circle’s position, radius, and fill color via attributes. The circles vary in size and color, with an opacity of 0.708, arranged in a scattered pattern across the canvas. The implementation relies on D3’s data join method to render the shapes.

d3 intro

This example demonstrates basic SVG shapes—a blue circle and a magenta rectangle—rendered on an HTML page, with a yellow SVG canvas sized at 900 by 500 pixels. The page also includes commented-out D3 code that would select the SVG, set its dimensions, apply a light blue background, and append a circle at new coordinates. The visible output relies on static SVG elements, while the script shows the intended use of d3.select and d3.append for dynamic manipulation, though it is not executed due to the commented syntax.

d3

This example demonstrates a single red circle with a green stroke, centered inside a 500-by-500 SVG canvas. The code uses D3 v6 to select the SVG element, append a circle, and set its radius, position, and fill and stroke colors via attribute methods. The visualization anchors the circle using fixed pixel coordinates, while the body text is styled with a 13-em font size for a bold, minimal layout.

Drawing SVG shapes with D3

This example illustrates two methods for creating a blue SVG rectangle: a static, hand-coded SVG element and a dynamically generated rectangle via D3. The static bar is defined directly in the HTML markup, while the D3 bar is built by chaining `d3.select` and `.append` calls. The code uses d3.v7 to append an SVG and style the rectangle with a `fill` style, showing the same visual output achievable through both declarative and programmatic approaches.

Fork of Circles with D3

This example demonstrates how to create and position circles within an SVG element using D3.js. It shows a data-driven approach where an array of circle objects, each with coordinates, radius, and fill color, is bound to SVG circle elements via D3's selection and method-chaining API. The code uses the `select`, `selectAll`, `data`, and `join` methods to manage the DOM elements, and the `attr` method to set positional and styling attributes. Rendering is responsive to the container's dimensions, and the example includes a video tutorial explaining the general update pattern.
