This example demonstrates the fundamental D3 data-join pattern by binding an array of five numbers to SVG rectangles, with each rectangle's width proportional to its corresponding value. The code selects an SVG container, calls `selectAll('rect')` followed by `.data(data)` and `.enter()`, then appends rects with width attributes set directly from the data. Using D3 v4 and vanilla JavaScript within an HTML page, it renders a simple vertical bar chart where bar heights are fixed by the `barHeight` variable and positioned via `translate` transforms. The visualization serves as a minimal introduction to D3's enter selection and chained attribute methods.

Learn D3 in 5 minutes

This example shows how to create a simple scatterplot-like visualization using D3’s data join pattern. Five circles are bound to an array of numeric values, with each circle’s radius determined by its corresponding data point. The code uses `d3.select`, `.data()`, and `.join()` to bind the array, then applies inline SVG attributes for positioning and CSS styles for fill and stroke colors. Rendering occurs in an SVG element, with D3 v7 loaded via a CDN script tag.

Learn d3.js

This example shows a minimal introduction to D3.js data binding using an array of five numbers. A static SVG container is set up in the HTML, while the JavaScript selects the body, binds the dataset to paragraph elements, and appends them with the corresponding text values. The visualization demonstrates the core `data()`, `enter()`, and `append()` pattern from D3 v4, alongside the use of `select()` and `text()`. It does not include interactivity or dynamic updates, serving purely as a basic learning exercise.

D3 Learning

This example demonstrates fundamental D3.js data binding and selection techniques through a simple bar chart. It loads an array of numeric values and maps them to SVG rectangles, with the height of each bar proportional to its corresponding data point. The code uses `d3.select` and `d3.selectAll` to manipulate DOM elements, while the `.data()`, `.enter()`, and `.append()` methods create the visual bars from the dataset. Additionally, it shows how to modify text content and styles on headings and paragraphs, illustrating both static selection and dynamic data-driven rendering in React.

Learn D3.js

A simple bar chart built with D3.js v5 demonstrates how to create an SVG visualization from a static array of data. The page displays a single titled bar chart rendered inside an SVG element, using D3’s selection and scale methods to map data values to pixel heights. The code also includes a separate Hello World message written to a DOM element, but the chart itself does not reference external data files or interactive features. The example serves as a minimal introduction to D3’s core SVG rendering workflow.

Learn D3.js

This example shows a simple bar chart built with D3.js v4, where each bar’s height corresponds to a value from a hardcoded JavaScript array of nine numbers. The chart is rendered as SVG inside an HTML page, with a title and a dedicated `<svg>` element. The code uses `d3.select` to set the SVG dimensions, `selectAll` with `data` and `enter` to create rectangles, and `attr` to position each bar via a `translate` transform based on its index. The bars are drawn from the bottom, using the SVG height minus the data value for the y-coordinate.

Learn D3.js

This bar chart visualizes a static dataset of nine numeric values using SVG rectangles. The example demonstrates how to construct a basic chart with the D3.js v4 library. The code sets the SVG canvas dimensions, calculates bar widths based on the data array length, and uses `d3.select` and `selectAll` to append `rect` elements. Each bar’s height and y-position are derived from the data values, with a `transform` attribute translating each rectangle horizontally. The chart is contained within an HTML page with a light background.

D3: Drawing a Bar Chart

This example demonstrates a basic bar chart built with D3 v7 in an SVG container, visualizing an array of 20 numeric values. The bars grow downward from the top of a 500×100 pixel canvas, with each bar’s height proportional to its data value multiplied by 4, and its fill color transitioning from dark to lighter blue based on the data. The chart also overlays each bar with white, 11px sans-serif text labels showing the exact data values, centered horizontally within each bar. The code uses `d3.select` to append SVG elements and the data-join pattern with `.enter()` to create rectangles and text nodes.

d3js Exercice 4 - selection, data

This example demonstrates a basic data join with D3.js v4, where an array of five numeric values drives the widths of five horizontal bars. The visualization shows how selection and data binding work by pairing each number with a `<div>` element, applying a CSS class and dynamic pixel widths based on the data. The code uses `d3.select` and `selectAll` to target the container, then the `.data()` method to bind the array, followed by `.attr()` and `.style()` to update the bars. Commented exercises hint at extending the example with `.enter()` and `.exit()` for dynamic element creation and removal, though the visible implementation only performs the initial update. The static bars, with heights and margins set via CSS, render from the hardcoded dataset.
