Let's make a face with D3.js

A D3.js v5 example demonstrates data-binding and enter/exit updates by rendering a row of fruit as SVG circles. Five apples appear initially, then one is removed after a second, and a third apple becomes a lemon after two seconds, illustrating dynamic updates to the DOM. Using `d3.select`, `scaleOrdinal`, and `range`, the code maps fruit types to fill colors and radii, with all circles positioned via `attr` and removed via `.exit().remove()`.

This example demonstrates a simple animated face made from D3.js circles, where fruits represent facial features. It shows five apples initially, then removes one apple and changes another into a lemon, updating the circle sizes and colors accordingly. Using D3 v5 APIs like `d3.range`, `d3.scaleOrdinal`, and selection methods like `selectAll`, `enter`, `merge`, and `exit`, it dynamically redraws the SVG circles in response to data changes. The visualization uses ordinal color and radius scales to map fruit types to red or yellow hues and varying sizes.

A D3.js selection demonstrates dynamic data binding by rendering fruit as SVG circles that appear, disappear, and change color. The data array starts with five apples, then removes one circle per second for three seconds, and finally replaces the first fruit with a lemon. The `data()`, `enter()`, and `exit()` methods manage the join, while `scaleOrdinal` maps fruit types to fill colors. The example uses `select`, `range`, and `attr` to manipulate the SVG canvas.

This example shows a fruit bowl visualization where apples and lemons are rendered as colored circles, with a face-like arrangement created through D3.js data joins. The code uses `d3.select`, `d3.range`, and `d3.scaleOrdinal` to map fruit types to red and yellow colors and different radii. It demonstrates enter, update, and exit selections, first removing an apple, then replacing one with a lemon via `setTimeout`. The SVG output is generated from a simple `fruitBowl` function that binds fruit data to circles.

This example demonstrates a dynamic fruit bowl visualization rendered as SVG circles, showing five apples that shrink to four and transform one into a lemon through timed transitions. The code uses D3.js v5 selection methods (`selectAll`, `enter`, `merge`, `exit`) with the `fruitBowl` module applying ordinal scales for color and radius via `scaleOrdinal` from d3. Data updates occur through `setTimeout` callbacks in `index.js`.

A data-driven update pattern renders a bowl of fruit as colored circles, transitioning from six red apples to a lemon over time. Using D3.js v5, the example demonstrates data joins with `selection.data`, `enter`, `merge`, and `exit` methods within a custom `fruitBowl` function. A `scaleOrdinal` maps fruit types to fill colors and radii, while `setTimeout` triggers sequential state changes—removing one apple and mutating another to a lemon—to show how the visualization reacts to data updates. The SVG is selected and populated from a static `index.html` file.

A data-driven face built from fruit demonstrates D3.js data joins with `scaleOrdinal` color and radius scales. The example renders five apples as red circles via SVG, then removes one fruit and changes a second to a lemon using `selection.data`, `enter`, `merge`, and `exit`. `setTimeout` triggers these updates, showing how D3 v5 handles dynamic data changes in a static HTML page with d3-selection and scales.
