This example shows a horizontal bar chart comparing 2018 population figures across continents, with each bar labeled by continent name and formatted population value. The SVG visualization uses D3 v5 scales—`scaleLinear` for the x-axis population range and `scaleBand` for the y-axis continent categories—with padding to separate bars. Data is parsed from a CSV string in `data.js` using D3’s `csvParse`, and numeric values are cleaned of commas and percentage signs. Rects and text are bound to the data via `selectAll` and `.enter()`, with bar widths scaled against the maximum population.

Making a barchart

This example shows a static bar chart of world population by continent for 2018, with values in absolute numbers and percentages of the world total. The chart renders as an SVG using D3 v5, reading inline CSV data parsed with `d3.csvParse`. The code maps each row, stripping commas from population figures and converting them to numbers, then logs the parsed array to the console. The visualization relies on D3 selections to access the SVG dimensions, though no axes or bars are explicitly drawn in the provided code.

Making a barchart

This example shows a horizontal bar chart of population figures for nine countries, drawn as an SVG. The chart maps population values to bar widths using D3’s `scaleLinear` and countries to vertical bands with `scaleBand`, then renders the bars as `rect` elements. Data is loaded from a CSV file with `d3.csv`, with population values multiplied by 1000, and axes are omitted, focusing solely on the bar geometries. The bars are styled with a steelblue fill via CSS, and the SVG is sized at 960 by 500 pixels.

Making a Bar Chart

The bar chart displays population figures for continents in 2018, with animated horizontal bars that grow to their final widths. The visualization uses `d3.scaleLinear` and `d3.scaleBand` to map population values to bar lengths and continent names to vertical positions, while `d3.transition` animates the bar growth. Numeric labels showing continent names and comma-formatted populations are positioned above each bar using `d3.format`. Data comes from a CSV string parsed with `d3.csvParse`, and the chart is rendered as SVG elements within a fixed 960×500 canvas.

Making a Bar Chart (Outtake)

This example shows a horizontal bar chart of continental populations in 2018, with each continent labeled with its total population. The chart renders as SVG rectangles sized by a `d3.scaleLinear` x-axis and positioned by a `d3.scaleBand` y-axis, with text labels added via SVG `<text>` elements. Data is parsed from an embedded CSV string using `d3.csvParse`, with population numbers cleaned via string replacement and numeric conversion. The data originates from Wikipedia’s list of continents by population.

Making a barchart

This example displays a horizontal bar chart of country populations using D3 v6, loading data from a CSV file and rendering it as SVG rectangles. The code imports `select`, `csv`, `scaleLinear`, `max`, and `scaleBand` from D3 to create linear and band scales that map population values to bar widths and country names to vertical positions. The bars are appended to an SVG element with dimensions specified in the HTML, and the population values are converted to numbers before rendering. The example also demonstrates loading D3 via UNPKG and using local ES6 modules for data generation and formatting utilities.

Making a barchart

This example shows a horizontal bar chart of population figures for the world’s most populous countries, using a CSV data source loaded with d3.csv. The visualization maps each country’s population to bar width via a d3.scaleLinear domain and a d3.scaleBand for categorical country labels, with axes generated by d3.axisLeft and d3.axisBottom. The chart renders as SVG inside a React application, with bars styled steelBlue and formatted using D3 v5.

Making a barchart

This example shows a horizontal bar chart of country populations, using D3 v6 to load data from a CSV file and render it as SVG rectangles. The visualization orders countries by descending population, with bar lengths scaled linearly and categorical spacing handled by `d3.scaleBand`. The code uses `d3.csv` to parse the data, `d3.scaleLinear` for the x-axis, `d3.axisLeft` and `d3.axisBottom` for labeled axes, and appends styled `<rect>` elements to the SVG.

Barchart

This example presents a vertical bar chart that compares the 2023 population of various countries, with values scaled in millions on the y-axis and country names on the rotated x-axis. The visualization is rendered as SVG, using D3 v5’s `scaleBand`, `scaleLinear`, and `axisBottom`/`axisLeft` to position and label the bars. Data is loaded asynchronously via `d3.csv` from a remote raw GitHub dataset, and bars are drawn with `rect` elements filled in skyblue. The chart includes custom tick formatting and axis titles for clarity.
