This example demonstrates the fundamental D3 margin convention by rendering a horizontal bar chart of the top 10 most populous countries from a UN population dataset. The visualization shows population values as proportional bars within an SVG, with the chart’s plotting area properly inset from the SVG edges using a margin object. Built with React and D3 v6, the code uses `d3.csv` for data loading, `scaleBand` for the categorical y-axis, and `scaleLinear` for the quantitative x-axis. A `<g>` element is translated by the margin offsets to position all rectangles correctly.

The Margin Convention

This example demonstrates the margin convention in D3 by rendering a horizontal bar chart of UN population data for 2019. The chart displays the top 10 countries by population using SVG rectangles, with scales created via `d3.scaleBand` and `d3.scaleLinear`. A margin object defines the inner plotting area dimensions, and a `<g>` element translates the chart into place. Data is loaded asynchronously from a CSV using `d3.csv`, and the visualization is built with React components and D3 v7.

The Margin Convention

This example demonstrates the margin convention in D3 by rendering a horizontal bar chart of the top 10 most populous countries from a UN population dataset. The chart uses a React component with D3 scales (`scaleBand`, `scaleLinear`) to position and size SVG rectangles within a translated group element, explicitly reserving space via a margin object. The x-axis encodes population in 2020, while the y-axis displays country names. The code applies D3's `csv` loading and React's `useState` and `useEffect` hooks for data fetching.

The Margin Convention

This example demonstrates the margin convention in D3 by rendering a horizontal bar chart of the ten most populous countries from a UN population dataset. The chart uses React to manage state and render SVG elements, with D3’s scaleBand and scaleLinear used to map country names and population values to pixel coordinates. A `<g>` element translates the chart by the specified margins, ensuring the bars are positioned within the allotted inner dimensions. The data is loaded asynchronously via `d3.csv`.

Margin Convention

This example demonstrates the D3 margin convention by rendering a horizontal bar chart of the top 10 most populous countries in 2020, using UN population data loaded via `d3.csv`. The chart employs `d3.scaleBand` for country positioning and `d3.scaleLinear` for population values, with an SVG `<g>` element translated by the margin object to inset the visualization. React manages the state and lifecycle, fetching and filtering the data before mapping it to styled `<rect>` elements inside the SVG.

The Margin Convention

This example demonstrates the margin convention in D3 by rendering a horizontal bar chart of the top 10 most populous countries from a UN population dataset (2020 estimates). The code uses D3’s `csv` loader, `scaleBand`, and `scaleLinear` to position and size the bars within an inner plotting area defined by explicit margins, while React’s `useState` and `useEffect` manage data fetching and component state. All SVG elements are generated declaratively through React, with the root group translated by the margin values to align the chart inside the fixed 960×500 viewport.

The Margin Convention

This example demonstrates the margin convention in D3 by rendering a horizontal bar chart of the top 10 most populous countries from UN population data. React manages the component state, fetching the CSV via `d3.csv` and storing the parsed data. The chart uses `scaleBand` for the y-axis country categories and `scaleLinear` for the x-axis population values, with bars drawn as SVG `rect` elements inside a translated group to respect the margin. The visualization shows how margins create space for potential axes while keeping the plot area clean.

The Margin Convention

This example demonstrates the margin convention in D3.js by rendering a horizontal bar chart of the top 10 countries by 2020 population from a UN dataset. The visualization uses SVG within a React component, with `d3.scaleBand` and `d3.scaleLinear` mapping country names to y-positions and population values to bar widths. A margin object reserves space around the chart, and the chart group is translated accordingly to align the bars within the inner plotting area.

The Margin Convention

This example demonstrates the margin convention in D3, displaying a horizontal bar chart of population data for the top 10 countries from the UN Population 2019 dataset. The visualization uses React’s useState and useEffect hooks to asynchronously load CSV data via d3.csv, then renders SVG rectangles scaled with d3.scaleBand and d3.scaleLinear. A margin object defines the inner chart area, with a translated `<g>` element positioning the bars within the SVG canvas.
