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.

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.

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.

This example shows a simple bar chart where 100 vertical bars fill the width of an SVG canvas, each bar representing an index from 0 to 99. The chart is rendered using React with the D3 library, specifically using `d3.select`, `d3.range`, and the `join` method to bind data and create the rectangles. The SVG elements are appended directly to the document body, with bars positioned horizontally at intervals of 20 pixels and a fixed height of 500 pixels.

Intro to D3.js

This example shows a bar chart built with D3.js, displaying numeric values as vertical bars with corresponding value labels above each bar. It reads from an embedded dataset of eight numbers and renders them using SVG rectangles via `d3.select`, `selectAll`, and `data().enter().append()`. The chart sets fixed width and height attributes, calculates bar widths based on dataset length, and positions bars with a `translate` transform. Text elements display each value in a distinct color. The code uses the `d3.v5` library and is structured with React-ready starter files.

This example demonstrates a basic bar chart visualization. It shows a dataset of seven numeric values, each rendered as a fixed-width blue bar whose height corresponds to the value. The chart is built using D3.js methods to select the HTML body, append a `div` for each data point, and apply the CSS class `bar`. The bar heights are set inline using a JavaScript arrow function, and the initial styling is defined within a CSS style block. The code relies on `d3.select`, `d3.selectAll`, `.data`, `.enter`, `.append`, `.attr`, and `.style` to construct the visualization. The data is hardcoded as an array.

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.

D3 Page Template

This example uses D3 v5 to render a simple bar chart. It creates an SVG canvas of 300 by 300 pixels, then defines a dataset of six numeric values. The code selects the SVG element, binds the data to it, and appends rectangles with widths proportional to the data values. Each rectangle’s height is fixed at 30 pixels minus a small gap, and its y-position is offset by index. The bars are uniformly colored steel blue. The rendering is purely SVG-based, using `d3.select`, `.append`, `.data`, and `.enter` to construct and position the bars.

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.
