This example demonstrates how D3’s join pattern creates initial DOM elements using `selectAll` and `enter().append()`. The code builds an SVG with five red circles, each positioned horizontally by multiplying the index by 120 pixels, using D3’s `range` to generate fruit data objects. It explicitly shows the enter selection, binding an array of `{type: "apple"}` objects to circle elements. React imports are commented out, leaving D3 v5 as the active rendering engine, with circle radius and fill set as static attributes.

D3 General Update Pattern

This example demonstrates the D3 general update pattern for animating data-driven visualizations with SVG circles. It initializes an array of fruit objects and uses D3 v7’s selection methods—including enter, exit, update, and merge—to handle dynamic data changes in a bar-chart-like layout. The code specifically creates five apples via `range` and maps them, then binds this data to circle elements using the `d3.select` API, with transitions and object constancy shown through styled SVG elements. The visualization relies on inline SVG attributes and CSS classes for appearance, without external datasets.

General Update Pattern Without Merge Function - Like React Render Function

This example demonstrates a general update pattern for SVG elements in D3, mirroring the behavior of a React render function. It initially renders five circles, each representing an "Apple" with a red color and radius of 50, positioned along the x-axis. After a delay, the third fruit changes its type to "Lemon", altering its fill to yellow and radius to 30. Then, a final fruit is removed, triggering the exit selection. The code uses `d3.selectAll`, `data`, `enter`, `exit`, and `remove` to manage the lifecycle of elements based on the data array.

General Update Pattern (Bowl of Fruit)

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.

D3 Practice

This example demonstrates how D3’s data join handles changing datasets, showing circles rendered from an array of five random integers. After drawing all circles, the code trims the data to three items, and the exit selection removes the extra circles from the SVG. It uses React 16.13 and D3 v6, with the `d3.randomInt` generator supplying values and D3’s selection methods (`data`, `enter`, `exit`) managing circle updates. The SVG is appended directly to the body, with no interactive behavior beyond the static removal.

D3: Drawing SVGs

This example demonstrates how to create basic SVG shapes with D3.js by rendering five circles of increasing radius. The code uses D3’s data join pattern, calling `selectAll`, `data`, `enter`, and `append` to bind an array of five numbers to circle elements. Each circle’s x-position is calculated from its index, its radius from the bound data value, and its fill, stroke, and stroke-width are set accordingly. The static SVG is 500 pixels wide and 50 pixels tall, with all circles vertically centered.

General Update Pattern

This example demonstrates the D3 general update pattern with React, using a row of fruit shapes that change over time. It shows how data joins handle enter, update, and exit selections as apples are eaten and replaced by lemons. The code uses `selection.data()` with a key function, `.enter()`, `.merge()`, and `.exit()` to manage SVG groups, circles, and text elements. D3’s `scaleOrdinal` maps fruit types to colors and radii, while `setTimeout` triggers state changes to the fruit array.

D3 General Update Pattern

A D3 visualization demonstrates the general update pattern for handling data joins with animated transitions. It renders five circles as apples using SVG, with the `fruitBowl` function managing enter, update, and exit selections via `selection.data()`, `.enter()`, `.merge()`, and `.exit()`. Sequential timeouts trigger state changes: removing a fruit, replacing an apple with a lemon (changing color and radius via ordinal scales), and filtering out another item. Each update animates circle radii from zero to a scaled value over 1000 milliseconds using `.transition().duration()`.

D3 v7 General Update Pattern Special Cases

This example demonstrates the D3 general update pattern in special cases where data arrays change dynamically. Using d3.selectAll and join, it renders SVG circles and text for fruits, updating the visualization as apples are eaten and replaced by lemons. The code employs d3.scaleOrdinal for color and radius mapping, with setTimeout driving sequential state changes. Each update merges entering and exiting elements, adjusting transforms and attributes to reflect the current fruit array.
