Circle Practice W/ D3

Fork of Circles with D3

This example demonstrates how D3.js creates and binds a dataset of circle objects to SVG elements, rendering them with varied positions, radii, and fill colors against a light green background. The D3 data join pattern, method chaining via `selectAll` and `attr`, and the general update pattern are used to handle repeated rendering safely. The visualization is built from a static JSON-like array of circle properties, with opacity applied for a subtle overlap effect, showcasing the core mechanics of D3’s declarative, data-driven approach to DOM manipulation.

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 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.

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.

A static SVG visualization displays six concentric circles centered at the same point, each with a progressively smaller radius and a distinct fill color (red, green, blue, yellow, purple, orange) outlined in black. The circles are rendered using D3 v7’s data join pattern, where an array of circle objects with explicit `cx`, `cy`, `r`, `stroke`, `strokeWidth`, and `fill` properties is bound to SVG circle elements via `.data()` and `.enter().append()`. The example demonstrates basic shape creation and attribute binding with D3, using a hardcoded dataset rather than external data or animation.

practice 1 - Circle around circle

This example displays a set of concentric circles centered on a fixed point, each filled with a different color and outlined in black. A small red circle is appended separately within the same SVG group. The visualization is built using D3 v5’s `select` and `append` methods to create SVG circles, with positions and radii driven by an array of JavaScript objects. The colored circles are stacked using `data.reverse()` to layer them from largest to smallest.

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.

This example demonstrates a fixed layout of colorful, semi-transparent circles drawn on a light green SVG background using D3.js. The visualization uses hardcoded data—an array of objects with x, y, radius, and fill color properties—to bind and render seven circles via `d3.select`, `.selectAll`, `.join`, and `.attr` calls. It showcases D3's data-join pattern and dynamic attribute styling, setting circle positions, sizes, colors, and a uniform opacity through method chaining.
