Circles with Canvas

Circles with D3

This example displays a scattered arrangement of colorful circles of varying sizes and positions across an SVG canvas. Each circle is rendered with a distinct fill color, creating a visually playful composition. The code defines a static dataset of circle properties and uses D3 v7’s data join pattern with `selectAll`, `data`, and `join('circle')` to bind and append SVG circle elements. Attributes like `cx`, `cy`, `r`, and `fill` are set directly from the data object.

Circles with D3

This example displays seven translucent circles at fixed positions and sizes across a pale green canvas, each filled with a distinct neon color. The visualization demonstrates how D3’s `select` and `join` API can declaratively create and style SVG circle elements from a static array of coordinates, radii, and hex fill values. Opacity is set uniformly to 0.708 via an attribute, with the rendering driven by D3 7.8.5.

1 Circles with D3

A D3.js data visualization displays fourteen colored circles at fixed positions with varying radii and hex fills across an SVG canvas. The code imports circle data from a separate JavaScript module and uses D3's `select` API with a data join to append and configure each `circle` element. Rendering targets a 960 by 500 pixel SVG, with the visualization defined in a reusable function that binds the dataset to attributes like `cx`, `cy`, `r`, and `fill`.

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.

Circles with D3 Cleaned Up

Fourteen colored circles, each with a unique position, radius, and color, are rendered on a 960×500 SVG canvas. The visualization demonstrates a clean, data-driven approach to drawing circles using D3 v7. The code binds an array of circle data to SVG circle elements using `selectAll`, `data`, and `join`, setting the `cx`, `cy`, `r`, and `fill` attributes directly from each data object. The data is defined in a separate module and the visualization logic is contained in a reusable `viz` function, making the example modular and easy to extend.

Circles with D3

This example demonstrates how to draw a set of circles on an SVG canvas using D3.js version 7. Each circle is positioned with explicit x, y coordinates, has a defined radius, and is filled with a distinct color, resulting in an abstract layered composition on a light green background. The code uses D3’s `select` function and the data join pattern via `selectAll`, `data`, and `join` to bind an array of circle objects to SVG elements, then applies attributes like `cx`, `cy`, `r`, and `fill` through method chaining. The visualization is rendered dynamically by measuring the container’s dimensions at runtime, and the example includes a setup for hot reloading in a development environment.

Circles with D3

This example displays a static collection of eight colored circles of varying sizes and positions on an SVG canvas. Each circle’s radius, stroke color, stroke width, and fill color are defined in a JavaScript array and rendered using D3’s data join with `selectAll`, `data`, `enter`, and `append`. The visualization demonstrates basic SVG shape creation with D3 v7, using attributes like `cx`, `cy`, `r`, `stroke`, and `fill` to map data properties directly to visual elements.

circles in D3

This example displays a static collection of thirteen colored circles scattered across a 600-by-400 SVG canvas, with varying radii, positions, and fills in blue, orange, and purple. The visualization uses no D3 or JavaScript logic, relying solely on hand-coded SVG elements inside an HTML document, with each circle defined by explicit `cx`, `cy`, `r`, and `fill` attributes. The rendering approach is direct SVG markup, and the code includes no data binding, interaction, or transitions.
