Idempotent Reusable Barchart 101 with Lines

Idempotent Reusable Barchart 101

This example presents an animated, reusable bar chart that visualizes the proportion of single-detached houses in Canada from 1986 to 2021. Built with D3.js (v7.8.4), it uses the `scaleBand` and `scaleLinear` functions to map census years and percentages, while `axisBottom` and `axisLeft` render the axes. The chart is implemented as an idempotent function, allowing it to be re-applied cleanly to an SVG canvas when parameters change, with bars rendered as SVG rectangles.

Reusable Bar Chart

This example demonstrates a reusable bar chart built with D3 v5, rendering a monthly price series (January 2000 through December 2010) as an SVG. The chart uses a band scale for the categorical date axis and a linear scale for the price values, with axes formatted using compact number notation. The `barChart` function returns a configurable closure that exposes chainable methods—width, height, x, y, padding, and title—allowing the chart to be customized and reused. While the data includes 132 monthly data points, the visible bars appear relatively few, suggesting the chart is intended to be resizable and may currently render a subset or need responsive adjustment.

Towards Reusable Charts

This example demonstrates a reusable bar chart component built with D3.js (v3) following Mike Bostock's "Reusable Charts" philosophy. The chart renders income data for five countries from an embedded CSV file, using SVG for output. The code defines `d3.svg.myBarchart` as a modular function with configurable properties like margins, scales, and axis settings, allowing the same chart to be instantiated multiple times without global variable contamination. It implements ordinal and linear scales, along with D3's axis components and a custom grid-line generator, all drawn within a fixed 600×400 viewport.

Basic bar+line chart

This chart combines a bar chart and a line chart in a single SVG visualization, with bars representing one data series and a line overlaid for a second series. It is built as a reusable template driven by a CSV file, where column names for the x-axis, bar values, and line values are configured in the code. The x-axis uses a band scale for categorical years, while the y-axis is linear and shared by both series. Blue bars show the primary values, and a green line connects the secondary values, with a legend distinguishing the two. The chart includes axis labels, a title, and a hover effect on the bars.

Making a Barchart reusable code

This example demonstrates a reusable bar chart built with D3.js v5, displaying the frequency of letters in a dataset from the United Nations world population prospects. It uses `d3.scaleBand` and `d3.scaleLinear` to position bars, `d3.axisBottom` and `d3.axisLeft` for axes, and renders SVG elements. The chart exposes configurable width, height, and margin via accessor functions, and broadcasts a custom mouseover event through a `d3.dispatch` object. Data is loaded asynchronously from a CSV file using `d3.csv`.

Reusable Bar Chart

This reusable bar chart, built with D3 v3, visualizes CO2 emissions, education levels, and employment-to-population ratios across 24 countries, using an animated, multi-series dataset. It is implemented as a configurable D3 plugin via d3.svg.barchart, rendering to SVG with smooth transitions. The chart supports customization of margins, dimensions, scales, padding, animation duration, tick formatting, and accessor functions for the x- and y-values, as well as optional domain setters. A subtle animation introduces bars, which rise with a transition, and axes animate into place, including rotated x-axis labels. Hovering reveals values. This example was forked from Doug Dowson's reusable chart pattern.
