This visualization displays the 2020 populations of 30 countries as a horizontal bar chart, using a band scale for country names and a linear scale for population values. The chart shows bars in light green with blue tick marks on the axes, and includes a tooltip formatted with D3's `format` API to abbreviate large numbers (e.g., "1.2B"). Built with React and D3 v5, the code explicitly uses `scaleBand`, `scaleLinear`, and `max`, while a custom `useData` hook fetches CSV data from a GitHub repository. The SVG is rendered via React components (`AxisBottom`, `AxisLeft`, `Marks`).

A horizontal bar chart displays the populations of 30 countries in 2020, sorted by country name, with each bar’s length representing population in billions. Built with React and D3 v5, it uses `scaleBand` for the y-axis, `scaleLinear` for the x-axis, and SVG `<rect>` marks with tooltips via `<title>`. Data is loaded from a remote CSV using `d3.csv`, and axes are rendered by custom components (`AxisBottom`, `AxisLeft`) with tick formatting via `d3.format`.

This horizontal bar chart displays the population of 30 countries in 2020, ordered by country name, with green bars and blue axis lines. The visualization loads a CSV file from a GitHub gist using D3's `csv` function, then renders the data as SVG rectangles via React. D3's `scaleBand` and `scaleLinear` position the bars, while custom `AxisBottom` and `AxisLeft` components generate ticks using D3's `ticks` and `domain` methods. Population values are formatted with D3's `format` function using the SI format to abbreviate large numbers.

A horizontal bar chart displays the population of 30 countries in 2020, ordered by country name on the y-axis. A linear x-scale encodes population values, with formatted tick labels converting scientific notation to billions (e.g., “1.40B”). Built with React and D3 v5, the chart uses `scaleBand` and `scaleLinear` for axes, with SVG `<rect>` marks rendered from CSV data loaded via `d3.csv`. Axis ticks are styled with blue lines, and tooltips show the formatted population value on hover.

This bar chart displays the population of 30 countries in 2020, using a horizontal layout with country names on the y-axis and population values on the x-axis. The visualization uses D3 v5’s `scaleBand` and `scaleLinear` to position bars, while React components render the SVG elements. Data is loaded from a CSV file via `d3.csv` and formatted with `d3.format` to abbreviate large numbers, for example converting Gigas to Billions. Each bar includes a native SVG `<title>` tooltip showing the formatted population value.

This visualization displays the populations of 30 countries in 2020 using a horizontal bar chart, where each bar represents a country and its length is proportional to the population value. The chart includes labeled axes for countries and population, with population values formatted in a compact notation (e.g., "B" for billions). The visualization is built using React and D3 v5, with D3's `scaleBand` and `scaleLinear` functions handling the categorical and numerical scales. SVG rectangles are used to render the bars, and tooltips provide exact population values on hover. The data is loaded from a remote CSV file and processed using D3's `csv` function.

This visualization displays the populations of 30 countries in 2020 as a horizontal bar chart, using SVG rectangles rendered through a React component. The chart imports data from a CSV file hosted on GitHub, processing population values by multiplying the 2020 column by 1000. It uses D3 v5’s `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis, with automatic tick generation via `xScale.ticks()`. The `format` API converts large numbers into abbreviated labels, and tooltips show precise values using the `title` element.

A horizontal bar chart displays the populations of 30 countries for 2020, with bars colored light green and axes styled with blue tick lines. The visualization uses React with SVG rendering, leveraging D3 v5 utilities including `scaleBand`, `scaleLinear`, `max`, and `format` to map country names and population values. Population data is loaded from a CSV file via `d3.csv`, with axis labels and tick formatting applied through helper components.
