This example demonstrates a simple bar chart constructed from 25 randomly generated rounded values. The visualization uses D3 version 4.5.0, with the code generating a fresh dataset of integers between 0 and 29 and rendering each as a teal vertical bar. The chart employs D3’s `selectAll`, `data`, `enter`, and `append` methods to create div elements, with each bar’s height dynamically set via the `.style` method based on the data value multiplied by five. The animation metadata refers to the random generation process rather than a temporal transition.

15. D3 Power of Data Random

A dynamic bar chart displays 25 randomly generated values as vertical teal bars. The visualization uses D3.js version 4.5.0 to bind an array of random numbers between 0 and 30 to HTML div elements, setting each bar’s height proportional to its data value. The animation updates the bar heights, demonstrating how D3 can render and update data-driven visualizations.

Fork of D3 Power of Data Random

A dataset of 25 random values is rendered as a static bar chart, with each value encoded as the height of a teal bar. The code generates the random numbers between 0 and 30 in a loop, then uses D3's `selectAll`, `data`, and `enter` selection pattern to create `div.bar` elements. The chart is built using D3 v4.5.0, and the bar heights are set directly via inline styles based on each data point.

12. D3 Power of Data

A static webpage displays a simple bar chart built with D3.js, representing a small dataset of five numeric values. The visualization uses D3's selection and data-binding APIs to dynamically create and style HTML `div` elements, with each bar's height proportional to its corresponding data value. The chart appears as a series of teal-colored vertical bars aligned horizontally.

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.

67. D3 Randomized Data

A bar chart displays 20 vertical bars whose heights and blue color intensities correspond to values in a static array. Clicking the text prompt replaces the dataset with 20 new random integers between 0 and 24, then animates the bars and their value labels using `transition` with `delay` and `duration`. The chart uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with SVG `rect` and `text` elements. Data is updated via a click handler on a paragraph element.

D3 Power of Data More Points

An animated D3.js bar chart demonstrates the power of scaling data values through visual encoding. The visualization displays a dataset of 25 numbers, rendered as teal bars whose heights are directly proportional to their corresponding data points. Using D3's selection, iteration, and binding APIs, the code assigns each value to a DOM element and dynamically sets the CSS height property, multiplying each datum by a factor of five for visual clarity. The static HTML and CSS structure provide the initial bar styling, while D3 handles the data-to-visual mapping.

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.

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.
