This example shows a horizontal bar chart of amounts per person, with red bars scaled linearly along the x-axis and categorical names on a band scale along the y-axis. The visualization renders as SVG using D3 v5, loading data from a local CSV file via `d3.csv` and converting the numeric amounts with `+d.amounts`. Scales, axes, and rectangles are created with `d3.scaleLinear`, `d3.scaleBand`, `d3.axisLeft`, and `selection.enter().append('rect')`, with margins applied through a group transform.

Barchart a.h.v tutorial Curran

This example displays a horizontal bar chart of country populations from a CSV file, with each bar’s length proportional to its population value. The visualization uses D3 v5’s `csv`, `scaleLinear`, and `scaleBand` to map data to x and y positions, while `axisLeft` and `axisBottom` generate the axes. SVG rectangles are appended and styled with a teal fill via CSS. The chart includes margins and padding, and the population values are converted from strings to numbers with the unary plus operator.

Making a Barchart

This example shows a bar chart of letter frequencies, with bars colored steelblue and a hover effect that turns them red. It uses D3 v5 to load data from a CSV file, then creates linear scales for the x- and y-axes, and renders the bars as SVG rectangles. The chart includes axis labels and ticks formatted as percentages. The data is mapped and scaled, with the y-axis positioned on the right side.

Barchart using csv

This example presents a horizontal bar chart of country populations, with each bar’s length corresponding to its population value from a CSV file. Using D3 v4, it loads `data.csv` with `d3.csv` and renders SVG rectangles, scaled linearly on the x-axis and banded on the y-axis. The chart displays axes via `d3.axisLeft` and `d3.axisBottom`, applies margins through a translated group, and styles bars blue via CSS.

Barchart

This example shows a bar chart of example data from the d3-graph-gallery website, displaying one categorical value per country. The bars animate vertically with a staggered delay, and value labels fade in above each bar. The chart is built using D3 v7 with SVG rendering, using `scaleBand` and `scaleLinear` for scales, plus `axisBottom` and `axisLeft` for axes. Data is loaded via `csv` from a GitHub raw source, and the layout is managed by a custom spacing module.

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.

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 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.

D3: Basic Barchart

This example shows a basic bar chart of 20 numeric values rendered as SVG rectangles, with each bar labeled by its value in white text. The chart uses D3 v5 scales, including a `scaleBand` for the x-axis positioning and a `scaleLinear` for the y-axis height calculation. Data is bound via `selectAll("rect").data()`, with bars and text labels positioned using the scales. The code loads D3 from UNPKG and demonstrates simple SVG generation without axes or interactivity.
