This example shows a horizontal bar chart of the ten most populous countries in 2020, using a bar’s length to encode population size. It fetches United Nations population data from a CSV file via `d3.csv`, then renders the bars as SVG `<rect>` elements within a `<g>` group translated by a fixed margin. The chart uses `d3.scaleBand` for the y-axis country categories and `d3.scaleLinear` for the x-axis population values, with React managing the component state and data loading.

Population Bar Chart with Margin with Axes

A horizontal bar chart displays the ten most populous countries based on United Nations 2020 estimates, with population values plotted along a linear x-axis and country names along a band y-axis. The React component loads CSV data via `d3.csv`, then renders SVG rectangles and axis tick labels using `scaleLinear`, `scaleBand`, and `max` from D3 v6. The chart applies explicit margins to position axes, which are manually constructed from `xScale.ticks()` and `yScale.domain()` rather than using D3's axis generators.

Population bar chart

This example visualizes the 2020 populations of the ten most populous countries using horizontal bars, with country names on the y-axis and population counts on the x-axis. The visualization is implemented as a React component that loads CSV data through the d3.csv utility, then renders scaled SVG rectangles using d3.scaleBand and d3.scaleLinear for positioning and sizing. Data for each country is parsed from the UN Population 2019 dataset.

População Bar Chart 01

This example displays the ten most populous countries as horizontal bars, with bar width proportional to each country’s 2020 population estimate. The chart uses React state to load and parse the CSV data, then renders SVG rectangles with D3’s `scaleBand` and `scaleLinear` for positioning and scaling. The data originates from the United Nations 2019 population perspective.

Population Bar Chart With Margin Convention

This example shows a horizontal bar chart of the top 10 countries by 2020 population, using React to render SVG elements. The chart applies a common margin convention, translating a group element to inset the plotting area within a fixed 960×500 viewport. It uses D3’s `scaleBand` and `scaleLinear` to map countries and population counts to pixel coordinates, loading data from a CSV of UN population figures. Bars are drawn as `<rect>` elements inside the transformed group, demonstrating a clean separation between axes, labels, and content.

População Bar Chart 02

This example displays a horizontal bar chart of the ten most populous countries in 2019, based on United Nations population data loaded from a CSV file. It initially renders a loading state while fetching data, then uses D3’s `scaleBand` and `scaleLinear` to map country names and population values to positions and bar widths. The React component manages state and renders SVG elements, including grid lines and axis labels, with D3 v7 functions like `max` and `ticks` to compute scales and tick values. The chart updates directly from the fetched dataset, showing population counts along the horizontal axis.

Population BarChart (React & D3)

This example displays the ten most populous countries as a horizontal bar chart, with each bar’s length proportional to its 2020 population estimate. The visualization loads CSV data from a GitHub gist using `d3.csv` and renders an SVG through React components. Scales are constructed with `d3.scaleBand` for the categorical country axis and `d3.scaleLinear` for the continuous population axis, while gridlines and axis ticks are generated via `xScale.ticks()`. The chart updates reactively as data arrives asynchronously.

Bar Chart

This example shows the top 10 most populous countries in 2020 as a horizontal bar chart, with country names on the y-axis and population on the x-axis. The chart uses React to render SVG elements, with d3.scaleBand and d3.scaleLinear for positioning, and d3.format for axis tick labels that abbreviate large numbers. Data loads from a CSV file of the United Nations World Population Prospects 2019, filtered to the first ten rows. Hovering over a bar reveals a tooltip with the formatted population value.

Bar chart

This example displays the top 10 most populous countries for 2020 as a horizontal bar chart, using rectangular SVG elements scaled by population size. The data comes from a UN Population CSV file, loaded with `d3.csv`. React manages the component state and rendering, while D3 v7 provides `scaleBand` for country positions on the y-axis and `scaleLinear` for population on the x-axis, with `max` determining the domain.
