This visualization displays the top 10 most populous countries in 2020 as horizontal bars, with bar length proportional to population. The React component loads the UN population dataset via d3.csv, then renders an SVG using scaleBand for the categorical country axis and scaleLinear for the population values. The chart fills the entire browser window (width and height set to window dimensions) and updates only after the data loads, initially showing a large “Loading…” message. The code uses React hooks (useState, useEffect) to manage the asynchronous data fetching and D3’s scale functions for mapping data to pixel coordinates.

UN Population 2019 Bar Chart

This example displays the top 10 most populous countries as horizontal bars, with bar length encoding each country’s 2020 population from the UN World Population Prospects 2019 dataset, though no axes or labels guide interpretation. The React app loads CSV data via `d3.csv`, sorts by population, and renders SVG rectangles using `d3.scaleBand` for the y-axis country positions and `d3.scaleLinear` for the x-axis population values. The chart updates when data finishes loading, initially showing a loading message.

United Nation Population

This bar chart displays the top 10 most populous countries in 2020 based on United Nations population data, using horizontal bars scaled by population size. The React-based visualization employs D3 v6 utilities like `scaleBand` and `scaleLinear` to map country names and population values to SVG coordinates, with tick marks and gridlines generated from the x-axis scale. Data is loaded asynchronously from a CSV file via D3's `csv` function and rendered through React's state management and SVG output.

UN Population Bar Chart

This example shows a horizontal bar chart of the top 10 countries by population from the UN’s 2019 dataset. It uses React state to load and store the CSV data, while D3’s `scaleBand`, `scaleLinear`, and `max` utilities compute the bar positions and widths. The SVG bars render across the full window height, sized proportionally to each country’s 2020 population. The code loads the data asynchronously with `d3.csv` and displays a loading message before the chart appears.

UN population countries

A bar chart displays the top 10 most populous countries in 2020 using UN population data, with horizontal bars sized by `Population` values. The React app loads CSV data via `d3.csv`, filters the first ten rows, and renders SVG `<rect>` elements using `d3.scaleBand` for the y-axis country categories and `d3.scaleLinear` for the x-axis population scale. The chart updates after an asynchronous data fetch, showing a loading state before the visualization appears.

UN Population Bar Chart Refactored

This example shows a horizontal bar chart of the top 10 most populous UN countries for 2020, with country names labeled on the y-axis and population counts on the x-axis. The visualization is rendered as SVG in a React component, using D3 v6 scales (scaleBand and scaleLinear) to map data, with separate XAxis and YAxis components drawing gridlines and tick labels. Data loads asynchronously from a CSV file via d3.csv in a custom useData hook, and React manages the component lifecycle.

Bar Chart

This bar chart displays the top 10 most populous countries based on 2020 UN Population data, with horizontal bars showing each country’s population count. The visualization uses React with D3 v5’s `scaleBand` and `scaleLinear` to map country names and population values to screen coordinates. SVG `<rect>` elements render the bars, while custom axis components generate tick marks and labels using D3’s `ticks()` and `format()` APIs, with population values formatted using the SI prefix format (e.g., “1.4B”).

UN population graph

This visualization displays the top 10 most populous countries using horizontal bars, ordered by country name with population shown on the x-axis in billions. The chart is built with React and D3 v5, using `scaleBand` for the categorical y-axis and `scaleLinear` with a maximum domain for the numeric x-axis. Data comes from the UN Population 2019 CSV, loaded via `d3.csv`, and rendered as SVG. Axis components and tick marks are generated from `d3.ticks`, formatted with `d3.format`, with tooltips showing exact values via SVG `<title>` elements.

UN World Population 2020

This example shows the top 10 most populous countries in 2020 using a horizontal bar chart, with each bar’s length proportional to the population from the UN World Population Prospects 2019 dataset. It loads the CSV data with d3.csv, transforms the 2020 column into numbers, and renders the bars as SVG rectangles using React’s useState and useEffect hooks. The chart uses d3.scaleBand for the categorical y-axis and d3.scaleLinear for the population scale, with the bars positioned and sized via the React map function.
