51. D3 Bar Chart

28. D3 Bar Chart Blues

A bar chart displays a fixed dataset of 20 numeric values in a viewport 500 pixels wide and 100 pixels high. Each bar’s height is proportional to the data value, scaled by a factor of four, and its horizontal position is computed from the array index and overall width. The bars are rendered as SVG rectangles using the D3.js v4.5.0 library, with a dynamic fill color that transitions from dark to lighter blue based on the data value. This example demonstrates simple data-driven styling without any animation or interactive elements.

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.

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.

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.

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.

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.

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.

52. D3 Bar Chart Scales

This example demonstrates a flexible, scalable bar chart built with D3.js (v4.5.0), using ordinal and linear scales to map a static dataset of 20 values to SVG rectangles. The chart uses `d3.scaleBand` for the x-axis positioning with padding and `d3.scaleLinear` for y-axis height, rendering bars and white value labels. The bars’ fill colors are dynamically computed from their values, creating a gradient from dark to light blue. The visualization appears static with no animation or interactions.
