This example displays a horizontal bar chart of population data for ten countries, sourced from a UN population CSV loaded via `d3.csv`. The React components `AxisBottom`, `AxisLeft`, and `Marks` render the axes and bars, using `scaleBand` and `scaleLinear` from d3.v7 to compute positions and widths. The visualization introduces a y-axis left with a band scale and an x-axis bottom with a linear scale. The SVG rendering shows the largest population bar extending nearly the full chart width while smaller bars are proportionally shorter. The chart is built with a loading state that displays "Loading..." until the asynchronous data fetch completes.

Refactored Bar Chart

This interactive bar chart displays population data for ten countries in 2020, sourced from a UN dataset loaded via d3.csv. The visualization shows horizontal bars ordered by country, with population values mapped to bar width using d3.scaleLinear and d3.scaleBand for positioning. The React component structure separates axis and mark rendering into modular files, with SVG elements generated from scales and mapped data. Custom AxisBottom and AxisLeft components handle ticks and labels, while Marks renders the rectangular bars.

refactored bar chart

This example shows population data for ten countries as a horizontal bar chart. React components render the SVG, while D3 scales and axes handle positioning: `scaleBand` maps country names to vertical bands, and `scaleLinear` maps population values to bar widths. The chart uses data from the UN Population 2019 dataset loaded via `d3.csv`, with custom `AxisBottom`, `AxisLeft`, and `Marks` components.

Refactored Bar Chart

This example displays a horizontal bar chart showing the 2020 population for ten countries listed in a UN dataset. The chart loads CSV data using the d3 `csv` utility and renders React SVG components for the plot. D3's `scaleBand` and `scaleLinear` are used for the y- and x-axes, respectively, while custom React components (`AxisBottom`, `AxisLeft`, `Marks`) generate the tick marks, labels, and rectangular bars. The visualization is drawn with SVG inside a React application, with the chart area offset by margins defined in the container.

Refactored Bar Chart

This example is a horizontal bar chart showing the populations of ten countries, derived from the 2020 column of a UN Population dataset loaded as CSV. It displays the data using SVG `<rect>` marks positioned by a d3 scaleBand for countries on the y-axis and a d3 scaleLinear for population on the x-axis, with axes rendered as custom React components. The chart is built with React and d3 v6, separating data loading in a `useData` hook and using functional components like `AxisBottom`, `AxisLeft`, and `Marks` to create a clean, refactored implementation.

refactored bar chart

This example shows a horizontal bar chart of population data for ten countries from a UN 2019 dataset. The visualization uses React to render SVG elements, with D3 v7 scales (`scaleBand` and `scaleLinear`) positioning the bars and axes. Custom React components (`AxisBottom`, `AxisLeft`, `Marks`) construct the tick lines, labels, and rectangles based on the data, while `useData` fetches and parses the CSV via `d3.csv`.

Refactored Bar Chart

This example presents a horizontal bar chart showing the population of the top 10 countries from a UN Population dataset. The chart uses React components to render SVG elements, with D3’s `scaleBand` for the categorical country axis and `scaleLinear` for the numeric population axis. The visualization is split into modular components, including `AxisBottom`, `AxisLeft`, and `Marks`, which draw the ticks and rectangles. Data is loaded asynchronously via `d3.csv`, and the chart updates upon data arrival.

Refactored Bar Chart

This example presents a horizontal bar chart of United Nations population data for ten countries, sourced from a CSV file. It shows population values for 2020 using the D3 scale functions `scaleBand` and `scaleLinear` to map countries and populations to SVG coordinates. React components render the marks and axes, with `AxisBottom` drawing tick lines and labels, and `AxisLeft` displaying categorical labels. The chart is built declaratively, avoiding explicit loops, by mapping over scales and data within the component JSX.

Refactored Bar Chart

This example presents a horizontal bar chart of the top 10 countries by population for 2020, sourced from a UN population CSV file. The visualization uses React with D3 v5 utilities to load and scale the data, rendering SVG via React components. `scaleBand` positions country labels on the y-axis, while `scaleLinear` maps population values to bar widths, with reusable `AxisBottom`, `AxisLeft`, and `Marks` components structuring the chart.
