Country population data

UN data

This bar chart displays the top ten countries by population in 2020, based on UN population data loaded from a CSV file. The visualization uses React for component structure and D3 v7 for scales, axes, and SVG rendering. The `scaleBand` positions the country labels on the y-axis, while `scaleLinear` maps population values to bar widths, with gridlines and tick labels generated from the x-scale. The data is fetched asynchronously via `csv()` and sorted alphabetically before being rendered as SVG rectangles.

bar chart

This bar chart displays the top 10 countries by 2020 population, with horizontal bars encoded by length and ordered by country name. The visualization uses React to manage state and render SVG elements, while D3 v7 handles data loading via `csv()` and scales through `scaleBand` and `scaleLinear`. Population data comes from a UN gist CSV file. Loading text appears until data arrives, and the chart currently lacks axis labels or text annotations.

Bar Chart Population

This interactive bar chart displays the top 10 most populous countries in 2020 according to UN population data. It uses React state to hold the CSV-loaded data and renders the visualization as an SVG. The chart implements D3's `scaleBand` for the categorical country axis and `scaleLinear` for the population axis, with axes drawn from D3's `ticks()` method. Rectangles represent each country's population, sized using the computed scales within a defined margin layout.

Bar Chart

This bar chart displays the top 10 countries by population for 2020, using horizontal bars ranked from largest to smallest. The visualization is built with React and rendered as SVG, leveraging D3 v7’s `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. Population values are loaded via `d3.csv` from a UN dataset and formatted with SI notation, converting “G” to “B” for billions. Axes are generated by custom React components, and hover tooltips appear through native SVG `<title>` elements.

Population Bar Chart

A horizontal bar chart displays the top ten countries by 2020 population from a UN dataset loaded via `d3.csv`. The chart uses React hooks (`useState`, `useEffect`) to manage data fetching and rendering, with SVG rectangles sized by `scaleLinear` for population values and positioned by `scaleBand` for country names. The visualization updates once the CSV data is parsed and sorted, presenting a clean, static comparison of population sizes without interactivity.

Bar Chart Countries Population

This bar chart displays the top 10 most populous countries in 2020, using horizontal bars where length represents population. The visualization is rendered as an SVG via React, with scales created using d3.scaleBand for the y-axis and d3.scaleLinear for the x-axis. Data is loaded asynchronously from a CSV file containing UN Population data, fetched with d3.csv. Each country is drawn as a rectangle with width proportional to its population value.

UN Population Data

A horizontal bar chart displays the populations of ten countries in 2020, sourced from UN data loaded via a CSV file. The visualization uses React to render SVG elements, with D3 v6 scales (scaleBand and scaleLinear) positioning bars and axes. Custom React components handle the axes and bars, with native SVG `<title>` elements providing tooltips. Population values are formatted using D3's `format` function, converting values like billions into abbreviated labels.

Sylized Bar Chart

This stylized bar chart displays the top 10 countries by population using data from the UN Population 2019 CSV. The horizontal bars are rendered as SVG rectangles, with country names along the y-axis and population values on the x-axis, formatted using D3's `format` function to convert values into billions. The chart uses React components for the axes and marks, with D3's `scaleBand` and `scaleLinear` for positioning, and includes a tooltip on each bar showing the population value via a native SVG `<title>` element.
