This example demonstrates how D3 selections manage the lifecycle of SVG circles through enter, update, and exit phases. Randomly generated data from a custom `data` function initially renders five blue circles, which are then updated to grey with a fixed radius of 11. The code explicitly uses `d3.select('svg')`, `.selectAll('circle')`, `.data()`, `.enter()`, `.exit()`, and `.remove()` while applying chained attribute and style modifications. Although an update with ten circles exists, it remains commented out, so only the initial static rendering is visible.

D3 Selections

This example demonstrates how D3 selections bind data to SVG elements. It renders five circles across the viewport, each with a random radius between 10 and 50, generated by a custom `Data` function using `d3.range`. The `Circles` module applies a re-usable selection pattern with `selectAll`, `data`, and `join` to create and style the circles. The main script uses `d3.select`, appends an SVG sized to the window, and calls the circle component, showing a modular approach to D3 v7 development in an ES modules setup.

d3 selections

This example demonstrates animated, data-driven updates of SVG circles using D3’s selection API. A set of circles oscillates vertically and horizontally, with their count varying sinusoidally over time. The code uses `d3.select`, `d3.range`, and the classic pre-v6 `selectAll`, `enter`, `merge`, and `exit` methods to manage additions, updates, and removals, running on a 60 FPS timer. It relies on D3 v6.6.1, rendering SVG with real-time animation.

D3 Selection Exploration

This example demonstrates D3 selections and data joins by generating a row of 15 static circles across an SVG canvas. The visualization shows how `selectAll` combined with `data` and `enter` creates elements from an array of numbers. Using `d3.select` and `range`, it appends circles with a fixed radius and x-coordinate to the full-window SVG. The code relies on the core D3 selection API and SVG rendering, with no interaction or dynamic updates.

D3 selection examples

This example demonstrates dynamic selection and updating of SVG circles using D3's modern `select` and `join` APIs. Fifteen circles animate horizontally across the window, with their vertical positions following a sine wave that shifts over time. The code uses `d3.select` to target the body, `d3.range` to generate data, and the `.join()` method to handle enter, update, and exit selections for circle elements, updating every frame via `setInterval`.

D3 Selection Exploration

This example demonstrates D3’s selection and data-join mechanics by continuously generating a changing set of circles. A `setInterval` updates the data array, whose length and positions vary with a sine wave, and the `svg.selectAll('circle').data(data).join('circle')` pattern creates or removes circles to match. The code uses D3 v7’s `select` and `range` functions, renders as an SVG animation, and updates element attributes (`cx`, `cy`, `r`) every 10 milliseconds.

D3 Selection Practice

Fifteen circles, arranged in a sine-wave pattern across the viewport, demonstrate basic D3 data joins and selections. The example uses D3 v6's `select`, `range`, and `selectAll().data().enter().append()` to bind an array of numbers to SVG circle elements, positioning them with `cx` and `cy` attributes. Rendered as an SVG in a full-window `<svg>` element, it shows how D3's functional attribute syntax derives coordinates from the bound data. The circles are static, with no interactions or transitions.

D3 Selection Exploration (Enter - Update Selections Clearly Separated)

This example demonstrates the D3 enter-update pattern by animating a set of fifteen circles along a sine wave. Every five seconds, the data array is regenerated, and the code clearly separates the enter selection—which appends new circles with `circles.enter().append('circle')`—from the update selection that repositions existing elements via `circles.attr('cx', ...)` and `circles.attr('cy', ...)`. Using D3 v7 with SVG, the visualization shows how identical data keys map to existing nodes, avoiding duplication. The animation loops indefinitely using `setInterval`, and the rendering adjusts to the full browser window size.

This example shows how D3.js creates and positions circles within an SVG container, using a data-driven approach where each circle’s coordinates, radius, and fill color come from an array of objects. The code demonstrates the D3 General Update pattern with `selectAll('circle')`, `.data(data)`, and `.join('circle')`, followed by method chaining with `.attr()` calls to set visual properties. It also sets the SVG dimensions from the container’s `clientWidth` and `clientHeight`, and applies a background color via `.style()`. The example relies on D3’s selection and data binding APIs, with data hardcoded in the script.
