This example visualizes the magnitude of changes in database object counts, such as Fields and Tables, using horizontal bars that extend either above or below a central baseline. Green bars indicate positive changes, while red bars represent negative changes, with bar height proportional to the absolute value of the change. The chart is built with D3 version 2 and relies on the underscore.js library for data transformation, using D3’s linear scale to map change magnitudes to pixel heights. A tooltip displays the item name and its signed change value on mouseover, while the bars are positioned absolutely within a relative container based on the sign of the change.

bar negative table #2

This example presents a table of margin values for four locations, using horizontal bars to compare positive and negative results. Each row shows a location name beside a bar extending left or right from a central zero line, colored dark orange for negative values and steel blue for positive ones. A third column summarizes each entry with a label like “Humpty” or “Dumpty” and the absolute value. Built with D3 v3, it uses `d3.scale.linear`, `d3.tsv` for data loading, and SVG elements such as `rect` and `line` to draw the bars and gridlines.

D3 Bar Chart

This interactive D3 v4 bar chart displays two datasets of numbers as vertical steel-blue bars with value labels and a y-axis. Clicking the Update button toggles between a 10-element ascending dataset and an 8-element descending one, demonstrating the enter, update, and exit pattern. The code uses d3.scaleLinear for the y-scale, d3.axisLeft for the axis, and transition().duration(500) to smoothly animate bar heights, positions, widths, and labels when the data changes. SVG rendering handles all visual elements.

Bar Chart with Negative Values

This bar chart displays both positive and negative values using horizontal bars, with positive values in steelblue extending right from the zero axis and negative values in darkorange extending left. The chart loads tab-separated data from a local file and renders it as SVG elements. Using D3 v3, the code employs a linear scale to position bars along the x-axis and an ordinal scale with rangeRoundBands for the y-axis. Two conditional logic paths compute the bar’s x-coordinate and width based on the value’s sign, while axes are drawn using d3.svg.axis.

Simple Vertical Bar Chart

This example presents a simple vertical bar chart that displays six financial metrics, such as total deposits and credit ratios, as orange bars with hover effects that darken the bars. The data is loaded from a tab-separated values file (data.tsv) containing label–value pairs. The visualization uses D3.js v3 with an ordinal x-scale and a linear y-scale formatted as percentages, alongside the d3-tip library to show tooltips with each bar’s exact value on mouseover. Axes are rendered via d3.svg.axis.

Gist a198389d0150b3f23ce2

This example demonstrates a simple column chart that handles negative values on the y-axis, using categorical data on the x-axis. It shows how bars extend above and below a zero baseline, with positive values in steelblue and negative values in brown. The chart is built with D3 v2, using an ordinal scale for the x-axis and a linear scale for the y-axis. It renders via SVG, with a reusable chart function that configures margins, axes, and bar dimensions based on the data.

Bar Chart I

This bar chart visualizes six numeric values—4, 8, 15, 16, 23, and 42—as horizontal bars whose widths are proportional to the data. The chart uses D3 v3’s `d3.scale.linear` to map the domain from zero to the maximum value (42) onto a pixel range of 0–420. Each bar is a styled `div` element with a steelblue background, white text, and a width set via the `style` operator. The code appends these divs using `d3.select` and `.selectAll("div").data(...)`, with the data bound to the DOM. The bars’ labels display the original values.

fresh block

A set of vertical bars represents five data values, with one bar highlighted in red and the rest in blue, showing a clear visual contrast for the largest value. The chart uses D3 v4 to bind an array of numbers to SVG rectangles, scaling bar heights linearly from a maximum domain of 2500 down to zero. The code applies the scale to position each rectangle’s top and height, while a fixed bar width and white stroke separate the bars for readability.

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.
