This D3.js v7 and React modular example displays United Nations population estimates for the top five countries in 2020, using an SVG bar chart. Left and bottom axes delineate country names and population values, with gridlines, while each bar’s length maps the quantitative scale. The code separates concerns into dedicated modules—`axisBottom.js`, `axisLeft.js`, and `marks.js`—each exporting reusable functions. It employs `scaleBand` and `scaleLinear` from D3 to position bars and ticks, uses the `csv` loader to fetch the remote data source, and renders the chart inside a React interface with defined margins.

Fork of UN Population Bar Chart - Margins And Axes

This example visualizes United Nations world population data for the top five countries as a horizontal bar chart, using D3 v7 scales and React components. The SVG rendering applies explicit margins and generates both x- and y-axis tick marks with grid lines for value reference. The code uses `scaleBand` for country positioning, `scaleLinear` for population values, and `csv` to load the UN dataset, with bar heights adjusted by computed padding.

United Nations Bar Chart - Refactored

A horizontal bar chart displays the top 10 countries by 2020 population, using United Nations data loaded via D3's `csv` and rendered as SVG through React components. Population values from the CSV are parsed and converted to counts, with a linear scale mapping them to bar widths and a band scale for country positions. The visualization includes formatted axes with tick labels, a population axis label, and tooltips showing abbreviated values via D3's `format`. Custom React components (`AxisBottom`, `AxisLeft`, `Marks`) structure the chart, while D3 v7 handles scales, data loading, and formatting.

Axes with React and D3

This example renders a horizontal bar chart of United Nations population data for 2020 using React and D3.js. The chart displays the top ten countries by population, with a linear scale for the x-axis and a band scale for the y-axis. React manages the SVG rendering and state, while D3 utilities (`d3.csv`, `d3.scaleBand`, `d3.scaleLinear`) handle data loading and scaling. Axis ticks and labels are generated via D3’s scale methods, and the bars are drawn as SVG `rect` elements.

un population margin axis React

A horizontal bar chart displays the top ten countries by UN population data for 2020, sourced from a CSV file. Built with React and D3 v7, SVG rectangles represent values scaled by `scaleLinear` and banded by `scaleBand`. Custom `AxisBottom` and `AxisLeft` components render tick marks and labels, while the `useData` hook asynchronously loads and parses the dataset.

Axes with React & D3

A bar chart displays United Nations population estimates for 2020 across ten countries, with country names on the y-axis and population values on the x-axis. The example integrates React (using `useState` and `useEffect` hooks) with D3 utilities, including `csv`, `scaleBand`, `scaleLinear`, and `max`. D3 loads the CSV data and computes scales, while React renders SVG elements—axis ticks, labels, and rectangles—within a single `<g>` group. The chart uses rendered SVG with manual gridlines and text labels.

Axes with React & D3

This example builds a horizontal bar chart of United Nations population data for 2020, showing the top five countries by population size. It loads the CSV data with d3.csv, then uses React's useState and useEffect to store and manage the fetched data before rendering. Axes are manually constructed with d3.scaleBand and d3.scaleLinear, with tick marks and labels drawn as SVG elements. The bars and axis ticks are generated as React components, using d3's max and tick utilities to compute scales and intervals from the data.

Axes With React & D3

This bar chart displays the top 10 countries by 2020 population, with horizontal bars ranked vertically. The visualization uses React for component structure and state management, while D3’s `csv` loads and parses the UN population data, and `scaleLinear` and `scaleBand` map values to pixel positions. SVG elements—including `rect` bars and axis ticks—are rendered directly by React, with D3’s `max` and `ticks` methods driving the axis generation. The chart adapts to the browser window size and includes labeled axes.

Refactored Bar Chart

This example shows a horizontal bar chart of UN population data for 2019, displaying the top 10 countries by population. The chart uses React components to render SVG bars and axes, with D3 utilities like `scaleBand` and `scaleLinear` for positioning and scaling. Data is loaded asynchronously via D3’s `csv` parser, and React’s `useState` and `useEffect` hooks manage the data fetching and state. The axes and marks are separated into reusable React components, demonstrating a modular approach to building visualizations.
