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.

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.

SVG fundamentals

This example demonstrates the fundamental building blocks of SVG rendering with D3.js, creating 15 circles positioned across the screen using a sine wave pattern. The code imports `select` and `range` from d3, appends an SVG element to the body sized to the full window, and uses the data join pattern with `selectAll`, `data`, and `enter` to create circles. Each circle receives a fixed radius of 20 pixels, with horizontal positions computed as multiples of 50 and vertical positions determined by the sine function. The visualization serves as a minimal, self-contained introduction to creating SVG shapes with D3's data-binding approach.

More basics of JS

Rendering five circles in an SVG via a React-started D3 v5 data join, this example demonstrates enter, update, and exit selections over time. It uses `d3.select` to manage the SVG, `d3.range` to generate an array of objects, and `d3.scaleOrdinal` to map domain values like "baseball" and "cube" to fill colors. After two timed `setTimeout` calls, one circle exits with a thick black stroke while another updates its fill from white to dark green.

Circles with D3

This example shows a set of seven colorful circles scattered across an SVG canvas, each with a distinct size, position, and fill color at 70% opacity. It demonstrates core D3.js v7 concepts including data binding, the General Update Pattern, and method chaining via `select`, `selectAll`, `data`, and `join` to render `circle` elements. The visualization uses static, data-driven coordinates and colors defined in a JavaScript array, rendered through an HTML import map loading D3 from a CDN. The code also showcases the `join` API for creating SVG circles within a container sized to the viewport.

Fork of Circles with D3

This example showcases five static, semi-transparent circles scattered across an SVG canvas, each with a distinct size, position, and color. The code uses D3 v3’s `select` and data joins to bind an array of circle objects to SVG elements. Rendering is driven by setting attributes like `cx`, `cy`, `r`, and `fill` directly from the data, with a fixed opacity value of 0.5. The visualization is a minimal demonstration of D3’s declarative approach to creating simple geometric shapes from a hardcoded dataset.

Hello D3

This example demonstrates basic SVG shapes—circles, rectangles, lines, and paths—styled with CSS classes and inline attributes. It shows how to compose geometric primitives within nested groups, applying transforms like `scale()` and `translate()`, and using both CSS rules and presentation attributes for fill, stroke, and stroke-width. The visualization uses HTML5 `<svg>` elements directly in the markup, with JavaScript and CSS linked externally, and does not include any data or interactive behavior.

Fork of Circles with D3

This example demonstrates how to create and update SVG circles with D3.js, using a data-driven approach where each circle’s position, radius, and fill color are bound to an array of objects. The code employs D3’s `select`, `selectAll`, `data`, and `join` methods to manage DOM elements, while method chaining sets circle attributes like `cx`, `cy`, `r`, and `fill`. It also shows how to set the SVG container’s dimensions from the parent element’s client size. The visualization serves as a tutorial illustration of D3’s general update pattern, with data defined inline rather than loaded externally.

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.
