This refactored bar chart displays the top 10 countries by population from a 2019 UN dataset, using horizontal bars with a yellow circular background. The visualization is built with React and D3 v7, employing `scaleBand` for the categorical y-axis, `scaleLinear` for the quantitative x-axis, and rendering SVG rectangles via the `Marks` component. Axes are constructed with explicit D3 tick and domain mappings, while the `useData` hook fetches and parses CSV data with `d3.csv`, converting population strings to numbers for the initial loading state.

Refactored Bar Chart

This bar chart visualizes the top 10 countries by 2020 population using data from the UN Population 2019 dataset, loaded via D3’s `csv` utility. Built with React and D3 v5, it encodes population with a linear x-scale (`scaleLinear`) and country names with a band scale (`scaleBand`) for the y-axis. The SVG rendering is composed of custom components for axes (`AxisBottom`, `AxisLeft`) and bars (`Marks`), with React state managing the asynchronous data loading.

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 visualizes the population of the top 10 countries from UN Population 2019 data as a horizontal bar chart. The chart uses D3 scales (`scaleBand` and `scaleLinear`) to position bars and axes, while React components render the SVG elements. The code separates AxisBottom, AxisLeft, and Marks into distinct React components, uses a custom `useData` hook to load and parse the CSV with d3.csv, and supports blank ticks as axis labels. The visualization highlights a modular, refactored approach to building reusable chart components.

Refactor Bar chart

This bar chart visualizes the population of the top 10 countries in 2020, using horizontally-oriented bars. Built with React and SVG, the example decomposes the visualization into reusable components: `AxisBottom`, `AxisLeft`, and `Marks`. It uses `d3.scaleBand` for the categorical y-axis, `d3.scaleLinear` for the population x-axis, and `d3.max` for domain calculation. Data is loaded asynchronously from a CSV file via a custom `useData` hook, which fetches and parses the UN Population 2019 dataset.

Refactored Bar Chart

This bar chart displays population data for the top ten countries from a UN 2019 dataset, with horizontal bars and labeled axes for easy comparison. Built with React, it uses a custom `useData` hook to load the CSV via D3's `csv` utility, then renders bars and scales using React's state management and SVG elements. D3's `scaleBand` and `scaleLinear` map country names and population values to coordinates, while `ticks` generate grid lines and labels, all within an SVG canvas created through ReactDOM.

Refactored Bar Chart

A horizontal bar chart displays the top 10 countries by population for 2020, using UN population data loaded via D3's `csv` utility. The React app renders SVG rectangles through the `Marks` component, with scales from `d3.scaleBand` and `d3.scaleLinear` positioning bars and axes. Reusable `AxisBottom` and `AxisLeft` components generate tick marks and labels. The chart is built with React 16.9, D3 v7, and SVG rendering, isolating data-loading logic in a custom `useData` hook.

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 example shows a horizontal bar chart of the top ten countries by population in 2020, using UN Population data. The visualization is built with React and D3 v6, where D3 utilities like `scaleBand` and `scaleLinear` compute the chart scales. The code refactors the visualization into modular components, with separate files for the axes (`AxisBottom`, `AxisLeft`) and the bars (`Marks`), demonstrating a clean separation of concerns. The chart is rendered as SVG, and the data is loaded asynchronously using the `csv` function from D3.
