Forked from SVG face

Five red circles represent apples in a bowl, rendered as SVG elements inside a 960×500 viewport. The example demonstrates D3’s general update pattern using `selectAll`, `data`, `enter`, and `exit` to manage circle creation and removal. A `fruits` array initializes five apple objects, then `pop()` removes one, triggering a re-render that deletes the corresponding circle via `exit().remove()`. Using D3 v6 and React-like render logic, it shows how data joins keep visuals synchronized with changing data.

Bowl of Fruit - General Update Pattern

This is a general update pattern example built with D3 v5 and the React framework, rendered as SVG. It shows a row of five apples that are drawn as circles, with a single fruit (the middle one) changing from an apple to a lemon after a one-second delay. The code uses D3's `select`, `scaleOrdinal`, and `range` APIs to map fruit types to colors and radii, and it demonstrates the enter, merge, and exit lifecycle for updating SVG circle elements.

Bowl of fruit - General update pattern

Five circles represent apples in a row, rendered as SVG via React and D3 v5. The visualization demonstrates D3's general update pattern: new fruit enters, existing fruit updates its position and color, and removed fruit exits with a shrink animation. Timed JavaScript events modify the fruit array, triggering transitions that move circles horizontally, change an apple to a lemon, and delete items. The code uses D3's selection, merge, and exit methods with a one-second transition duration for all changes.

Bowl of Fruit - General Update Pattern

Five apples rendered as SVG circles in a bowl demonstrate D3’s general update pattern. The code uses `d3.scaleOrdinal` for color and radius, binding fruit data to circles via `selectAll` and `data`. A `setTimeout` removes the last apple, while another changes the third apple to a lemon, triggering enter, update, and exit selections with `circles.enter()`, `circles.attr`, and `circles.exit().remove()`. The visualization shows how D3 handles dynamic data changes smoothly.

fruit bowl - general update pattern

Five red circles represent apples in a row, using D3 v5’s general update pattern with `selection.data`, `enter`, `exit`, and `remove`. The initial `range(5)` dataset renders all circles, then after one second a `setTimeout` removes the last apple, triggering an exit transition that deletes the corresponding circle from the SVG.

Bowl of Fruit - General Update Pattern1

This example demonstrates the D3 general update pattern by showing a row of five apples that transition over time: one apple is removed, and another apple changes into a lemon. It renders SVG circles using d3.selectAll and a data join, with scaleOrdinal for color and radius. The update, enter, and exit selections are handled explicitly, with exit().remove() deleting the removed circle. Data is managed in a plain JavaScript array, and a render function reapplies attributes, simulating a component-based approach with D3 v5.

Bowl of Fruit - General Update Pattern

Five circles represent apples in an SVG bowl, then change over time as the data updates. The example demonstrates D3’s general update pattern with `selection.enter`, `merge`, and `exit` to handle added, removed, and modified fruit. It uses `d3.scaleOrdinal` for color and radius, with `setTimeout` to sequentially pop, replace, and filter items from a JavaScript array, triggering a re-render via the `fruitBowl` function.

Bowl of Fruit - General Update Pattern

Five apples appear as red circles in a row, then transform over time as one is removed, another changes to a yellow lemon, and a third is deleted. This demonstrates the D3 general update pattern, using the d3.select and d3.range APIs within a React framework. The fruitBowl function performs the data join, merging enter and update selections, while transitions animate the circle radii and horizontal positions over one second, and exit selections shrink before removal.

Bowl of Fruit - General Update Pattern

Five circles are drawn as apples in a bowl, each at a fixed horizontal position. The visualization demonstrates the general update pattern: initially five apples appear, then the last is removed, the third apple changes into a lemon, and the second item is deleted. Using D3 v5’s `selectAll`, `data`, `enter`, `merge`, and `exit` methods within the custom `fruitBowl` function, the SVG circles transition smoothly. Ordinal color and radius scales map fruit types to specific colors and sizes, with data defined in `index.js`.
