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.

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.

Drawing SVG Shapes with D3

This example contrasts hand-written SVG markup with D3-generated SVG for drawing a simple bar shape. It shows a static green rectangle created directly in HTML using the `<rect>` element, and an identical rectangle produced dynamically via D3’s selection and append methods. The page uses `d3.select`, `append`, `attr`, and `style` to construct and style the SVG node in the DOM. The code relies on D3 v7 loaded from a CDN and does not use any data binding or scales.

Drawing circles with d3

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 SVG

This example demonstrates basic SVG shapes rendered with D3.js, showing how static geometric elements can be drawn directly in a web page. It displays a blue circle and a rectangular outline with a stroke, positioned at fixed coordinates within an SVG canvas of 500 by 960 pixels. The code uses the D3.js library to construct the SVG container and its child elements, with circle and rect tags defining the visual properties. The rendering approach relies on D3’s SVG manipulation capabilities, though no data binding or dynamic updates occur, as the shapes are hardcoded in the HTML structure.

Rect with data

This example shows a single blue circle centered within a 200-by-200 SVG canvas. The circle has a black stroke and a fill color of #69a3b2, demonstrating basic shape rendering with D3 v5. The code creates an SVG container using `d3.select("#circle").append("svg")`, then appends a circle element with attributes for position, radius, stroke, and fill. Though the title references a rectangle, the visualization actually renders a circle using standard D3 selection and attribute methods.

D3 Rectangle Examples

This example demonstrates the creation of six SVG rectangles using D3.js, each illustrating different visual properties such as fill color, stroke width and alignment, offset positioning, and corner radii. It also includes a seventh set that arranges three colored rectangles with varied dimensions and placements. The code uses D3’s selection and append methods to build SVG elements, with data defined as inline JavaScript objects specifying attributes like width, height, and style. The page is rendered at a fixed size and relies on D3 2.4.5.

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.js in action!

This example shows a red square with a thick black border rendered inside an SVG canvas, demonstrating basic D3.js DOM manipulation. The code uses `d3.selectAll('svg')` to target the SVG element and appends a `rect` with attributes for position, size, stroke, and fill. It relies on the D3 v5 library loaded from a CDN, and renders the shape as pure SVG geometry without any data binding or interaction. The result is a static visual, illustrating how D3 can directly create and style SVG elements.
