This example displays a horizontal bar chart of population data for the ten most populous countries, sourced from the UN Population 2019 dataset. The visualization uses React components to structure the SVG rendering, with D3 v7 handling the scales for both axes. The `scaleBand` and `scaleLinear` functions map country names and population values to pixel positions, while reusable `AxisBottom`, `AxisLeft`, and `Marks` components generate the tick marks, labels, and rectangular bars via SVG `<rect>` elements.

Refactored Bar Chart

This example displays the population of the top ten countries from the UN Population 2019 dataset as a horizontal bar chart. React components render the SVG marks and axes, while D3 utilities handle the data loading and scale calculations. The chart uses a `scaleBand` for the categorical y-axis, a `scaleLinear` for the quantitative x-axis, and `csv` for fetching the data. Each component (`AxisBottom`, `AxisLeft`, `Marks`) is modularized and receives the scales and data via props, highlighting a reusable and refactored architecture for visualization.

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.

Refactored bar Chart

This data visualization example shows a horizontal bar chart displaying the populations of the ten most populous countries, using data from the UN Population 2019 CSV file. The chart is constructed using React components to render SVG elements, with D3 utilities (d3.csv, scaleBand, scaleLinear, max) handling data loading and scales. The code separates concerns into distinct functional components—AxisBottom, AxisLeft, and Marks—each receiving scale and data props. The axes and rectangles are rendered as SVG elements based on the population values from the "2020" column.

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 shows a horizontal bar chart of the 12 most populous countries using UN population data from 2019. React renders SVG bars, with D3’s `scaleBand` and `scaleLinear` mapping country names and population values. Custom `AxisBottom` and `AxisLeft` components generate tick marks, while `Marks` draws the rectangles. The chart loads CSV data via `d3.csv` and uses React hooks for state management.

Refactored Bar Chart

This example shows a horizontal bar chart of population data for the top 10 countries in 2020, using React to render SVG elements. It fetches the UN Population dataset via `d3.csv`, then uses `scaleBand` and `scaleLinear` from D3 v7 to map country names and population values to screen coordinates. The chart is composed of three reusable React components for the bottom axis, left axis, and the bars themselves, with each axis tick and bar generated as separate SVG elements. The visualization demonstrates a modular, component-based approach to building D3 charts within a React framework.

Refactored Bar Chart

This example shows the top 10 most populous countries as horizontal bars, with country names on the left axis and population values on the bottom axis. The chart is built with React and D3 v5, using `scaleBand` and `scaleLinear` for positioning, and renders SVG rectangles via the `Marks` component. Data comes from the United Nations World Population Prospects 2019, loaded with `d3.csv`. Axes are drawn using custom components that leverage D3’s tick methods.

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.
