This example renders a horizontal bar chart of the top ten countries by population, using data from the UN’s 2020 population estimates fetched via `d3.csv`. It shows each country’s population as a bar, with the chart built in React and D3 v7. The code computes scales with `scaleBand` for the categorical country axis and `scaleLinear` for the numeric population axis, then draws SVG `<rect>` elements for each bar. Rendering is handled declaratively through React state and the `d3.csv` promise.

Rendering Data with React & D3

This example uses React and D3 to render a horizontal bar chart of the top 10 most populated countries for 2020, sourced from a CSV file of UN population data. It fetches the data with `d3.csv`, scales bars with `d3.scaleBand` and `d3.scaleLinear`, and maps each country to an SVG `<rect>` element via React components. The chart displays population counts as bar widths, with a "Loading..." state shown before data arrives.

UN Pop data basic bar chart top 10

This example displays the top 10 countries by 2020 population from a UN population prospects CSV, rendered as horizontal bars in an SVG. It uses React with D3 v7, loading and slicing the data via `d3.csv`, then mapping it through `scaleBand` for the y-axis and `scaleLinear` for the bar widths. The chart updates responsively, showing each country’s name alongside its population, with the data retrieved from a GitHub gist.

Rendering Data with React & D3

A horizontal bar chart displays the populations of ten countries for 2020, sourced from UN population data loaded via `d3.csv`. The chart renders as SVG using React components, with a `scaleBand` for the y-axis country names and a `scaleLinear` for the x-axis population values. Bars are generated through the `BarRect` component, each filled with random RGB colors, while custom `AxisBottom` and `AxisTop` components draw tick marks and labels, with population formatted in billions using `d3.format`.

Rendering Data with React

This example visualizes the top 10 countries by 2020 population as a horizontal bar chart rendered with SVG. The code loads UN population data from a CSV file using `d3.csv`, processes the rows, and stores the result in React state via the `useState` and `useEffect` hooks. D3’s `scaleBand` and `scaleLinear` position the bars, while React maps the data to `<rect>` elements. A loading message displays until the data arrives, with the chart updating once React state is set.

UNPop

This bar chart displays the top 10 countries by population for 2020, sourced from a UN population CSV. The visualization uses React to manage state and render an SVG, while D3 v6 handles data fetching via `csv()`, scaling with `scaleBand` and `scaleLinear`, and the `max` aggregation. Each country’s population is mapped to a rect’s width, with countries positioned along the y-axis. The chart highlights population magnitudes through horizontal bars, relying on D3’s declarative API for layout and React for component lifecycle.

Rendering (barchart) data with react and d3

A bar chart displays United Nations population estimates for 2020 across ten countries, using horizontal bars scaled by population size. The visualization loads CSV data via `d3.csv` and manages the asynchronous result with React’s `useState` and `useEffect` hooks. React renders SVG rectangles, while `d3.scaleBand` and `d3.scaleLinear` compute bar positions and widths. The data pipeline converts the population string to a number and filters to the top ten entries before rendering.

Rendering Data in bar chart

This example displays a horizontal bar chart of population data for the top 10 countries, sourced from the UN Population 2019 CSV. The chart uses React to render SVG rectangles, with scales created by d3.scaleBand and d3.scaleLinear to position bars and axes. Custom React components (AxisBottom, AxisLeft, Marks) draw the axes and bars, while the useData hook loads and parses the CSV via d3.csv. The visualization effectively compares population sizes through bar lengths, with country names labeled on the left axis.

Rendering un-population data with React & D3

This example shows a horizontal bar chart of the top 10 countries by 2020 population, using React state to manage the data and D3 scales to position the bars. It loads the un-population CSV via `d3.csv`, maps the population values, and renders SVG rectangles with `scaleBand` and `scaleLinear`. Grid lines and tick labels are generated from `xScale.ticks()`. The chart uses React hooks (`useState`, `useEffect`) to fetch and update the data, with D3 v6 providing the scaling and CSV parsing utilities.
