A single dark circle fills the center of an SVG canvas, its radius and position computed directly from the viewport dimensions. The example demonstrates minimal D3 v5 selection and attribute manipulation, using `d3.select` to target the `svg` element and `circle.attr` to set `r`, `cx`, and `cy` based on hard-coded height and width values. Rendering occurs entirely through SVG, with no data binding or interaction. The code also links an external stylesheet and loads D3 from a CDN.

d3 Starter

This visualization demonstrates a minimal starting point for building with D3, displaying a single large circle centered near the left side of an SVG canvas. The code uses D3 v7's `select` function to target the existing SVG element, then appends a circle with `append`, setting its radius to 300 and horizontal position to 300 via the `attr` method. While minimal, it establishes the core pattern of selecting, appending, and styling SVG elements.

Test D3

This example displays a single circle centered within an SVG canvas, sized to half the height of the 960×500 viewport. It demonstrates minimal D3.js v5 usage, where the `select` function targets the existing SVG element and `append` creates the circle shape. The circle’s radius, x-coordinate, and y-coordinate are set via the `attr` method, using the hard-coded dimensions for height and width. The page is styled with CSS, setting a monospace font and removing margins, while the circle itself is rendered with default black fill.

D3 Example

A minimal D3.js example renders a set of circles on an SVG canvas, positioning each circle based on an array of objects with `x` and `y` coordinates. The code uses D3's data join pattern—`selectAll`, `data`, `enter`, `update`, and `exit`—to append, update, and remove circle elements dynamically. The visualization is embedded in a plain HTML page with D3 version 3.5.5 loaded from a CDN, and the circles are drawn with a fixed radius of 30 pixels.

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.

Hello D3

This example demonstrates the simplest possible D3.js visualization: a single SVG circle centered on a blank canvas. The code imports the `select` function from D3 v6 via an ES module, selects the `<svg id="viz">` element, and appends a circle element with a radius of 200 pixels, rendered as SVG. It showcases the fundamental pattern of selecting, appending, and styling elements using D3’s declarative API. The accompanying README links to a video for beginners, emphasizing the learning-focused intent of the minimal code.

Untitled

A single orange circle is rendered inside a small SVG canvas, demonstrating basic D3.js selection and manipulation. The example uses `d3.select` to target the circle element by its ID, then modifies its radius, stroke, and fill color via the `attr` and `style` methods. The code shows how D3 can directly update SVG attributes and CSS styles on existing DOM elements, with the circle initially defined in static HTML markup.

SVG Starter

This example displays a single red circle rendered inside an SVG canvas. It serves as a minimal setup for SVG-based visualization, showing how a static shape can be styled directly using D3. The code uses D3 v5's selection and styling API (`d3.select` and `.style`) to apply the fill color, while the circle itself is defined in plain SVG markup within the `index.html` file. The page also imports a separate stylesheet for global typography and layout.

First D3 try

A single red circle is drawn at the center of a 960 by 500 pixel SVG canvas, with its radius set to half the canvas height. The example demonstrates a minimal first use of D3 v5 within a React framework, where the `d3.select` function targets the SVG element and `.attr` sets the circle’s radius, x-coordinate, and y-coordinate. The code uses the D3 `append` method to create the SVG circle, rendering directly to the SVG output.
