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 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 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

A grid of hand-coded pastel circles on a white SVG canvas, positioned at fixed coordinates with specified radii and fills. The example serves as a minimal demonstration of D3's selection and join API: `select()` targets the SVG element, while the `selection.selectAll(...).join(...)` chain in `viz.js` binds the imported data array to `circle` nodes, using `.attr()` to map each datum’s `cx`, `cy`, `r`, and `fill` properties. The data originates from `data.js` as an exported array of objects.

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 displays seven colored circles, each with distinct positions, radii, and fill colors, laid out on a light green background. The visualization uses the D3.js library within a data-driven approach, binding circle elements to an array of data objects. It demonstrates D3's method chaining and data join pattern, where the `select`, `selectAll`, `data`, and `join` methods manage the SVG creation and attribute updates, including `cx`, `cy`, `r`, and `fill`.

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.

Fork of Circles with D3

This example showcases seven colorful circles placed across a light green SVG canvas, each with distinct positions, radii, and fill colors drawn from a hardcoded data array. The visualization demonstrates D3’s data binding and the General Update Pattern through chained method calls, using `selectAll`, `data`, and `join` to create circle elements. Each circle’s `cx`, `cy`, `r`, and `fill` attributes are set from the bound data objects, with a uniform opacity applied to all shapes.

Fork of Circles with D3

This example presents a static scatterplot-like arrangement of 14 colored circles on a 960 by 500 SVG canvas. Each circle is positioned using explicit `cx`, `cy`, and `r` attributes, with a distinct hexadecimal fill color. The code uses D3 v7’s data join pattern (`selectAll`, `data`, `join`) within a reusable `renderCircles` function, binding the `circlesData` array to SVG `<circle>` elements. The visualization directly renders this hardcoded dataset without any interaction or animation, demonstrating a clean, minimal approach to data binding and attribute assignment.
