Five vertical divs display a bar chart, each bar's height corresponding to a value in a small JavaScript array. The visualization demonstrates how D3 version 4.5.0 maps data to visual properties using a simple pipeline. The code uses `d3.select` to target the body, `selectAll` and `data` to bind the dataset, then `enter` and `append` to create divs with class 'bar'. A style function dynamically sets the `height` attribute in pixels, overriding the initial CSS. This example illustrates D3's core selectors and data-binding methods.

21. D3 Bar Chart Divs

A simple bar chart displays a dataset of twenty numeric values as vertically sized divs. The chart uses D3 v4’s data join pattern, calling `d3.select`, `.data`, and `.enter` to bind each number to a `div.bar` element. The height of each bar is set inline via `.style("height", ...)`, scaling the data value by five pixels. The static, non-animated visualization relies solely on HTML divs and CSS styling, with no axes or scales defined.

09. D3 Drawing Divs

This example demonstrates how to bind a simple array of numbers to HTML elements using D3.js, creating five div elements with a teal background class. The code uses the d3.select and data binding methods (selectAll, data, enter, append) to generate the visual elements. Each div is assigned the “bar” class with fixed inline CSS styling. The dataset values influence the number of rendered bars but not their size, as the visualization focuses on the fundamental pattern of entering data-driven DOM elements.

11. D3 Drawing Divs Spaced

Five teal bars appear in a row across the page, each representing a value from the static dataset `[5, 10, 15, 20, 25]`. Using D3 v4.5, the code selects the body, binds the data, and appends a `div` for each number. The bars are spaced with inline-block styling and margin, while each height is set dynamically via `.style('height', ...)` as the data value multiplied by five pixels. This example demonstrates the basic data-join pattern and the use of D3’s `.selectAll`, `.data`, and `.enter` methods to generate DOM elements.

26. D3 Bar Chart Heights

A simple bar chart displays twenty numeric values as vertical SVG rectangles. The chart uses a fixed width of 500 pixels and height of 100 pixels, with each bar’s height scaled by a factor of four. The code creates the visualization by selecting the body, appending an SVG element, and binding the dataset using `d3.select`, `.data`, and `.enter()`. Rectangles are positioned using `attr('x')` and `attr('y')`, with width calculated by dividing the total width by the number of data points, minus a one-pixel padding.

Hello D3 Version 6

This example demonstrates how to create a basic bar chart from an array of numeric values using D3 version 6. The chart renders vertical bars as colored div elements appended to the document body, with each bar’s height proportional to its corresponding data point. The code uses the d3.select, data, enter, append, and style methods to bind the dataset to new div elements and set their heights dynamically. The dataset is a plain JavaScript array of 20 numbers, and the rendering relies on the DOM rather than SVG or canvas.

D3 Bar Chart Rects

This example demonstrates a simple bar chart built with D3.js, where an array of twenty numeric values is visualized as a series of teal, inline-block rectangles. The chart uses D3's selection and data-binding API (`d3.select`, `.data`, `.enter`, and `.append`) to dynamically create `div` elements with a CSS class. Each bar’s height is set via the `.style` method, multiplying the data value by a fixed factor to produce a pixel height, resulting in an animated rendering of the dataset.

51. D3 Bar Chart

This is a simple D3.js bar chart that visualizes a numeric dataset of 20 values, displaying each value as a rectangle scaled in height and colored in varying shades of blue. The chart uses an SVG element sized 500 by 100 pixels, with rectangles positioned horizontally and vertically scaled by a factor of four. Each bar is labeled with its corresponding number, rendered in white text. The example demonstrates basic D3 v4.5.0 APIs including `d3.select`, `svg.selectAll`, `.data()`, `.enter()`, and `.attr()`, with a static dataset defined as an array of integers.

25. D3 Bar Chart Widths

This example demonstrates a bar chart with dynamic widths and spacing. It renders 20 rectangles in an SVG container, positioning each bar horizontally and calculating its width based on the dataset length with a fixed padding. The chart uses D3.js version 4.5.0, applying the `selectAll`, `data`, and `enter` pattern to bind the array of numbers to SVG `rect` elements. All bars are drawn with a constant height of 100 pixels, and the x-coordinates are computed using the index multiplied by the width divided by the dataset size.
