This example presents a simple bar graph built with d3.js v4, displaying county populations from a CSV file fetched via a remote URL. The chart uses `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis, with axes generated by `d3.axisBottom` and `d3.axisLeft`. Bars are rendered as SVG rectangles with a steelblue fill that turns brown on hover, and the data is loaded asynchronously with `d3.csv`. The layout is fixed to the viewport with margins and explicit SVG dimensions.

AI-generated description

This is a simple bar graph written using d3.js v4.

This graph is part of the code samples for the update to the book D3 Tips and Tricks to version 4 of d3.js.

Simple bar graph in v4

A simple bar graph displays population values for California counties, loaded from an external CSV file and rendered as SVG rectangles. The chart uses d3.scaleBand for the x-axis categories and d3.scaleLinear for the y-axis, with axes generated by d3.axisBottom and d3.axisLeft. Data is parsed via d3.csv, and bars change fill color on hover through CSS. The example demonstrates core d3 v4 data binding and SVG rendering in a fixed-width layout.

Population Bar Graph

This population bar graph displays county population data using a vertical bar chart. The chart encodes each county’s population with the height of a steelblue bar, which turns brown on hover. Built with D3 v4, it uses `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and SVG `rect` elements for the bars. The data is loaded from a remote CSV file via `d3.csv`.

Simple bar graph in v4

This example shows a simple bar chart of sales figures per salesperson, rendered as SVG rectangles. It uses D3 v4 with a `d3.scaleBand` for the x-axis and a `d3.scaleLinear` for the y-axis, pulling data from an external CSV file. The chart includes bottom and left axes via `d3.axisBottom` and `d3.axisLeft`. Data is loaded asynchronously with `d3.csv`, and bar heights are calculated relative to the maximum sales value.

Making a bar chart with D3.js

This example shows a horizontal bar chart of country populations using D3.js v5, with data loaded from a CSV file and rendered as SVG rectangles. The chart uses `d3.scaleLinear` for the x-axis population scale and `d3.scaleBand` for the categorical y-axis, with `d3.axisLeft` and `d3.axisBottom` to draw the axes. Population values are formatted by multiplying the raw CSV numbers by 1000, and the bars are styled with a steelblue fill.

Making a Bar Chart!

This example displays a horizontal bar chart of country populations, with values read from a CSV file and scaled by 1,000. Using D3 v5, it employs `d3.csv` to load the data, `scaleLinear` and `scaleBand` to map population and country names to positions, and `axisLeft` and `axisBottom` to render axes. Rectangles are appended to an SVG group with margins, sized by the scales, and styled with a steelblue fill.

bar graph v2

A bar graph displays population estimates for four countries, sourced from a local CSV and rendered as SVG. The visualization maps population to horizontal bar length and country names to vertical positions, using a linear scale and a band scale. It is built with D3 v6, employing functions like `select`, `csv`, `scaleLinear`, `scaleBand`, and the `axisLeft` and `axisBottom` helpers. The chart includes styled tick marks, a title, and an axis label, with the population axis formatted in billions.

Let's make a bar chart with D3.js!

A bar chart maps country populations from a CSV file to horizontal rectangles. The chart uses D3 v5’s `scaleLinear` and `scaleBand` to position and size bars, with population values multiplied by 1,000 and rendered as SVG `rect` elements. Data loading relies on `d3.csv`, and the layout is fixed at 960 by 500 pixels. The example focuses on the fundamental steps of binding data to SVG shapes and encoding values through a linear scale.

Making a Bar Chart with D3.js

This example demonstrates a basic bar chart built with D3.js, mapping country populations from a CSV file to SVG rectangles. The code uses `d3.csv` to load the data, `d3.scaleLinear` for scaling, and `selection.enter()` to append rectangular elements. The chart reads the data.csv file, multiplies population values by 1,000, and renders static 300-by-300-pixel bars without axes or labels.
