A row of identical black rectangles is drawn on an SVG canvas, one for each value in a hardcoded array of twenty numbers. Using D3.js version 4.5.0, the code selects the SVG element, binds the dataset with `selectAll('rect')` and `.data()`, then appends rectangles via `.enter()`. All rectangles are initially positioned at x=0, y=0 with fixed dimensions of 20 pixels wide and 100 pixels tall, so the visualization currently shows no variation in height or position despite the differing data values.

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.

24. D3 Bar Chart Even

Twenty vertical SVG rectangles form a static bar chart from a hardcoded array of 20 numeric values. The bars are evenly spaced along the x-axis using a calculated offset based on the dataset length, with a fixed width and full chart height, so no data variation is encoded. The example uses D3 v4’s `d3.select`, `append`, `data`, and `enter` to bind the array and create the rectangles, demonstrating a basic SVG rect-based bar chart without axes or scales. An animation is not present in the visible code.

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.

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.

27. D3 Bar Chart Teal

This bar chart displays a static dataset of 20 numeric values, rendered as teal-colored rectangles in an SVG container. The code uses D3.js version 4.5.0 to bind the array of numbers to SVG `rect` elements, calculating each bar’s x-position, width, and height based on the dataset length and value. The bars are vertically scaled by a factor of 4, with a 1-pixel padding between them. The chart does not include axes, labels, or interactivity, focusing solely on the basic bar-encoding technique.

29. D3 Bar Chart Labels

This D3.js bar chart displays a static dataset of twenty numeric values as vertical bars. The SVG rendering uses blue-filled rectangles whose height and color intensity scale directly with the data value. Each bar includes a white, sans-serif text label positioned inside the bar, showing its corresponding value. The chart is constructed procedurally using D3's `select`, `append`, and `attr` methods, with no external data file.

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.

30. D3 Bar Chart Aligned

This example displays a static bar chart of 20 numeric values using D3 v4, with each bar rendered as an SVG rectangle and labeled with its corresponding data value in white sans-serif text centered within the bar. The chart uses a fixed SVG width of 500 pixels and height of 100 pixels, with bar heights scaled by a factor of four and a one-pixel padding between bars. Each rectangle’s fill color is a blue gradient calculated from its data value, and the labels are positioned inside the bars using `d3.selectAll` with data binding and `.attr` methods.
