Five red circles appear in a row on a dark blue canvas, resembling a simple face when viewed together. The example demonstrates the D3.js v5 selection API, using `select` to target the SVG element and the `range` function to create an array of fruit objects. The `render` function appends circles with the D3 `selectAll` and `data` methods, then removes one circle after the initial render by calling `fruits.pop()` and re-rendering, showing the exit selection in action. The rendering is SVG-based, with styling from the included stylesheet.

This example demonstrates a simple data-join workflow in D3.js, rendering a row of five red circles as “apples” and then removing them one by one over time. The code uses `d3.select`, `d3.range`, and the `data()` method with `enter()` and `exit()` selections to manage SVG circle elements dynamically. It also relies on `setTimeout` to trigger two successive updates, showing how `exit().remove()` cleans up removed data points. The visualization is rendered as an SVG inside a fullscreen, dark-themed page with large circular shapes.

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 how to create a simple face-like pattern using D3.js by rendering five red circles across the center of an SVG canvas. The visualization uses fruit objects as the data source, with each fruit type assigned to a circle. The code leverages D3’s `select`, `range`, and `enter().append()` methods to bind data and generate circle elements, setting their `cx` positions based on index and `cy` to the vertical center. The resulting static composition highlights basic data-binding and SVG shape creation in D3 v5.

A playful SVG face built from five apples, each represented as a circle with fixed facial features, demonstrates basic D3.js shape creation and data binding. The code uses `d3.select` and `d3.range` to generate an array of fruit objects, then renders them inside a static 960×500 SVG canvas. The face’s layout is hardcoded through SVG attributes rather than a force simulation or scales, and the styling relies on an external Ubuntu font and dark background. This example highlights how D3 v5 can manage simple data-to-element mappings without interactive transitions.

This example demonstrates the fundamental D3.js data-join pattern by rendering a row of red circles that function as a face. The code uses `d3.select` and `d3.range` to generate an array of fruit objects, then binds that data to SVG circles with `selectAll().data().enter()`. After an initial render, `fruits.pop()` removes one data element, and the `exit()` selection turns that circle black to visualize the removal. The SVG canvas measures 960×500 pixels, with circles spaced 120 pixels apart.

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.

Five D3-generated apples start as plain circles on an SVG canvas. Using data binding and `selection.enter()`, each fruit receives an interactive face made from additional circle elements, with positions tied to index-based spacing. The example demonstrates fundamental D3 v5 joins with `selectAll` and `attr` updates, rendering entirely through SVG as specified in the HTML document.
