This example shows a horizontal bar chart of the top 10 countries by population in 2020, loaded from a CSV file. The chart demonstrates the margin convention by offsetting a group of rectangles using an SVG transform. React state manages the asynchronous data loading with `d3.csv`, while the scales `scaleBand` and `scaleLinear` map country names and population counts to the inner chart dimensions. The bars are rendered as SVG `rect` elements within React’s declarative JSX structure.

The Margin Convention

This example demonstrates a horizontal bar chart of the top 10 most populous countries in 2020, using D3 scales to map population counts to bar widths and country names to vertical positions. The chart applies the margin convention, translating the SVG group by a fixed margin so the bars fit within the inner chart area. React state manages the fetched CSV data, loaded asynchronously via `d3.csv`, while `d3.scaleBand` and `d3.scaleLinear` handle the scales, and SVG `<rect>` elements render each bar.

The Margin Convention

This example demonstrates the Margin Convention for bar charts, showing the top ten countries by 2020 population as horizontal bars. It loads data from a CSV file using `d3.csv`, then uses React state and the `useEffect` hook to fetch and store the data. The chart is rendered as SVG, with `d3.scaleBand` mapping countries to the y-axis and `d3.scaleLinear` mapping population to the x-axis. A margin object defines padding, and the inner chart area is translated accordingly using an SVG `<g>` transform.

The Margin Convention

This example demonstrates a simple horizontal bar chart of the top ten countries by 2020 population, using data loaded from a CSV file. The chart applies the margin convention, reserving space around the plot area with a 20-pixel margin on all sides. The visualization uses React state to manage the data and renders SVG rectangles, with scales defined by `d3.scaleBand` for the y-axis and `d3.scaleLinear` for the x-axis. Population values are parsed from the CSV using D3’s `csv` utility.

The Margin Convention

This example shows a horizontal bar chart of the top ten countries by 2020 population, with the bars drawn inside a translated SVG group to demonstrate the margin convention. The chart uses React state to manage the loaded data and conditional rendering to display a loading message. D3 utilities load the CSV data from a GitHub gist, while `scaleBand` and `scaleLinear` position the bars and map population values to widths. The outer SVG measures 960 by 500 pixels, with a 50-pixel margin on each side that defines the inner chart area.

The Margin Convention

This example presents a basic bar chart using a horizontal layout, displaying the top ten countries by population for 2020. The bars are drawn as SVG rectangles, with their lengths proportional to each country's population value. The chart's position within the viewport is controlled by a fixed margin on all sides, demonstrating the standard convention of reserving space for axes and labels. The code loads data from a CSV file using D3's `csv` utility, then uses D3's `scaleBand` for the categorical country axis and `scaleLinear` for the quantitative population axis. React manages the rendering of the SVG elements, while D3 handles the data loading and scaling.

The Margin Convention

This example displays a horizontal bar chart of the top ten most populous countries for 2020, using a conventional margin layout to offset the visualization from the SVG canvas edges. The application loads its data from a CSV file via `d3.csv`, then uses `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the quantitative x-axis to size the rectangles. React manages the component state and conditional rendering, showing a loading message until the data arrives, while the final chart is drawn as SVG elements within a transformed group.

The Margin Convention

This example visualizes the top 10 countries by population in 2020 as horizontal bars. The chart uses the margin convention, arranging a 960 by 500 pixel SVG with a 20-pixel margin on each side. The code loads data from a CSV file using D3's `csv` utility, and then uses React state to manage the data asynchronously. Key D3 APIs include `scaleBand` for the categorical country axis, `scaleLinear` for the population axis, and `max` to compute the domain, with bars rendered as SVG `rect` elements within a transformed group.

The Margin Convention

This example demonstrates the D3 margin convention by rendering a horizontal bar chart of the top ten countries by 2020 population, loaded from a CSV file. The visualization separates the chart’s inner plotting area from its outer SVG bounds using a margin object, with a scaleBand for countries and a scaleLinear for population values. Built with React and D3 v7, the SVG rectangles are positioned via a translated group element, while the data is fetched asynchronously using d3.csv.
