This example displays a set of animated circles moving vertically and changing size in a sine-wave pattern. The visualization is built with D3.js and rendered as an SVG. The code dynamically generates new data points using a custom `makeData` function, and updates the circle positions and radii via the `vizData` function, which uses D3's `selectAll`, `data`, and `join` methods to efficiently update the scene. The animation is driven by a timer that increments a time variable, causing the circular nodes to oscillate smoothly.

D3 practice

An animated wave of circles moves across the screen, with fifteen evenly spaced circles rising and falling in a smooth sinusoidal pattern. Each circle is rendered as an SVG element, with its vertical position recalculated at 60 frames per second using a time-based sine function. The code uses D3’s `select`, `range`, and `join` methods to bind data and update the circle positions, while a `setInterval` drives the animation loop, updating a time variable that shifts the wave phase.

D3 Selection Exploration

This example demonstrates dynamic SVG circle generation and animation using D3 v7. An array of circles, generated from a sine-based function, continuously updates position and radius to create a flowing wave effect. The code uses D3's `select`, `selectAll`, `data`, and `join` methods to bind new data and manage enter/update/exit cycles. An interval-driven animation loop calls `vizData` at 60 frames per second, with data created by `makeData` using D3's `range` utility. The visualization runs in an HTML page with no external data sources.

animating data cleaner code

This example uses D3 v7 to create an animated, generative visualization of circles. It displays a dynamic sine-wave pattern where 10 to 15 circles move vertically and change radius over time, rendered as SVG elements on a full-window canvas. The animation runs at a 60 FPS interval, with each frame updating the `cx`, `cy`, and `r` attributes of the circles via `selectAll` and `.join`. The periodic motion is computed using `Math.sin` for both position and size, creating a smooth, evolving sine-wave composition.

3. D3

This example shows a group of ten to fifteen animated circles moving in a smooth, wave-like pattern across the screen, with their vertical positions and radii oscillating sinusoidally over time. The visualization is built with D3 v6 and rendered as SVG elements, with new circle properties updated 60 times per second using a `setInterval` loop and the data join pattern `selection.selectAll().data().join()`. The `makeData` function generates the dynamic coordinates using D3’s `range` helper, while the `vizData` module handles the attribute updates for `cx`, `cy`, and `r`.

Fork of D3 Selection Exploration

This example demonstrates animated data-driven circles that flow in a sine wave pattern across the screen. The visualization updates at 60 frames per second, with each circle's position and radius changing over time based on a mathematical function. The implementation uses the D3.js library's `select`, `selectAll`, and `.data().join()` API to efficiently bind array data to SVG circle elements. The `vizData` function applies `attr` calls for the `r`, `cx`, and `cy` properties, while a separate `makeData` module generates the dynamic dataset with trigonometric calculations.

D3 Selection Exploration

A set of animated circles undulates across the screen, their vertical positions and radii oscillating sinusoidally with a slowly changing phase. The visualization demonstrates data joins in D3 v6, using `selectAll`, `data`, and `join` to update SVG circle elements every frame via `setInterval`. Generated data from `makeData` feeds the `vizData` function, which binds new values for `cx`, `cy`, and `r` at 60 frames per second.

D3 Selection Exploration

This example demonstrates dynamic D3 selection and data binding by animating a set of circles that move and resize in a sine-wave pattern. Using `d3.select`, `selection.data`, and `.join`, it updates the SVG circle positions and radii every frame at 60fps via `setInterval`. The `makeData` function generates the x, y, and r values, while the `vizData` module applies the attributes. Rendering relies on SVG elements with no transitions, showing raw join behavior. The data is synthetic, derived from trigonometric functions, and the visualization fills the browser window.

makeData vizData of HTML Starter episode 5 makeData

This example animates a dynamic set of circles whose positions and radii oscillate over time. The visualization updates 100 times per second, using a sine wave to vary the number of circles between 1 and 19, while each circle’s y-coordinate and radius also fluctuate based on its index and time. The code uses D3’s `select` and `range` functions to build an SVG scene, with the `vizData` function applying a `join` operation to smoothly update circle attributes. Data is generated on the fly by the `makeData` function using trigonometric calculations, with no external data source.
