This example displays the top 10 most populous countries as horizontal bars, with bar length proportional to each country’s 2020 population estimate. The data comes from a CSV file of UN population figures, loaded via `d3.csv` and processed with a custom row function. The visualization uses React state to manage the data, and D3’s `scaleBand` and `scaleLinear` to compute bar positions and widths. Each bar is rendered as an SVG `<rect>` element, with the chart updating once the data loads. The page shows a loading message until the dataset is ready.

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.

Pathetic Bar Chart

This bar chart visualizes the top 10 most populous countries in 2020 using data from the UN Population 2019 dataset. A horizontal bar encodes each country’s population with a rectangle, positioned along a band scale and scaled by a linear scale from D3. The React app loads the CSV via `d3.csv`, stores it in state with `useState`, and renders the SVG bars through React’s DOM. Once loaded, the chart appears, replacing an initial “Loading…” text.

Pathetic Bar Chart

This example displays the top 10 most populous countries as horizontal bars, using a United Nations population dataset loaded via `d3.csv`. The bars render in SVG, with `d3.scaleBand` positioning each country along the y-axis and `d3.scaleLinear` mapping population values to bar widths on the x-axis. React manages the data state and renders each rectangle, while D3 handles the scaling and data parsing.

Pathetic Bar Chart

This bar chart displays the top 10 most populous countries based on the UN Population 2019 dataset, using a linear x-scale for population and a band scale for country names. The React app fetches the CSV via `d3.csv`, slices the first 10 rows, and renders SVG rectangles directly in the browser. The chart loads with a "Loading..." placeholder while the data is fetched asynchronously.

(margin convention) Countries by population (top 10)

A horizontal bar chart displays the top 10 most populous countries in 2020, with bar length encoding population size. The visualization uses React to manage state and render SVG elements, while d3-scale’s `scaleBand` and `scaleLinear` compute the y and x positions. Data is loaded asynchronously via d3.csv from a UN population dataset, then sorted and sliced to the first ten rows. The chart applies a margin convention, translating the inner group by `margin.left` and `margin.top` to position bars within the SVG canvas.

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.

Pathetic Bar Chart

This example presents a bar chart of the top 10 most populous countries using UN population data from 2019, loaded via d3.csv. The chart uses d3.scaleLinear for the horizontal axis and d3.scaleBand for the vertical country categories. It is rendered as an SVG with React, where each bar is a rectangle element positioned using the scales. The visualization dynamically fills the browser window based on its dimensions.

Pathetic Bar Chart vertical 1

This example displays the top 10 most populous countries as a series of horizontal bars, with bar width proportional to each country’s 2020 population. It uses React hooks to fetch and parse CSV data from the United Nations World Population Prospects, then renders an SVG with `d3.scaleBand` for vertical positioning and `d3.scaleLinear` for scaling bar lengths. The chart intentionally omits axes, labels, and other embellishments, focusing solely on raw bar lengths. The visualization is styled with a full-screen layout and a large "Loading..." placeholder while data is being fetched.
