This bar chart displays population estimates for ten countries in 2020, using data from the United Nations World Population Prospects 2019. The visualization is built with React and D3 v5, rendering bars as SVG rectangles via a modular structure. D3 scales—`scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis—handle the mapping, while separate components for the bottom axis, left axis, and marks help organize the code. The chart highlights an approach that separates concerns for easier reuse in other visualizations, with the loading state shown as plain text until data arrives.

AI-generated description

Refactoring

Ajuda a:

  1. o codigo principal fica menor e com significado semantico
  2. atividades posteriores de fork e modificacoes para usar em outras visualizacoes ficam mais faceis

Data: United Nations World Population Prospects 2019.

Refactored Bar Chart

This example shows a horizontal bar chart of population data for ten countries, using the United Nations 2019 population estimates. The chart displays the bars across a linear scale, with categorical country labels on the left axis and numeric tick marks on the bottom axis. Built with React and D3 v5, the visualization uses d3.csv to load and parse the data, d3.scaleBand for the y-axis, and d3.scaleLinear for the x-axis, rendering all marks as SVG rectangles. The code separates concerns into reusable components for the axes and marks.

Refactored Bar Chart

This example shows a horizontal bar chart of population data for ten countries, using the United Nations World Population Prospects 2019 dataset. The chart displays each country’s population for 2020 using SVG rectangles scaled by `d3.scaleLinear` and positioned with `d3.scaleBand`. The React components render the axes and marks, with `d3.csv` fetching the dataset and `d3.max` determining the x-axis domain. The visualization highlights a modular refactoring approach where axis and mark components are separated for clarity.

Refactor Bar Chart

A React-based bar chart built with D3 renders United Nations population estimates for 2020, showing the ten most populous countries. The chart uses `d3.scaleBand` for the categorical y-axis and `d3.scaleLinear` for the quantitative x-axis, with SVG rectangles representing each value. Axes are constructed as reusable React components (`AxisBottom`, `AxisLeft`) that map scales to tick marks and labels. Data is loaded asynchronously from a CSV file via D3’s `csv` function, and the visualization updates only after the data is fully fetched.

Refactored Bar Chart

This chart displays the 2020 populations of ten countries using horizontal bars, with country names on the y-axis and an x-axis for population values from the UN Population 2019 dataset. The D3 v5 scales `scaleBand` and `scaleLinear` compute the layout, while React components for axes and marks map the data to SVG `<rect>` elements. Population values are parsed from the CSV into numbers via `useData`, and the bars are rendered within an SVG canvas.

5) Bar Chart - Styling

This bar chart displays the top 10 countries by population in 2020, using data from the United Nations World Population Prospects 2019. The chart is rendered with SVG in React, leveraging D3 v5 scaleBand and scaleLinear for axes and positioning. Custom axis components generate ticks, while a marks component maps data to styled rectangles with tooltips. The chart uses the Poppins font, a teal fill for bars, and formats population values with d3.format for readability.

Refactored Bar Chart

This example presents a horizontal bar chart of country populations using React components to structure the visualization. The chart loads data from a CSV file containing 2020 UN population estimates, slicing the dataset to show the top ten countries. D3 v5 utilities handle data parsing and scale generation, with `scaleBand` for the categorical y-axis and `scaleLinear` for the quantitative x-axis. Each bar’s width corresponds to the population value, rendered as SVG rectangles within a React component hierarchy, with separate component files managing the axes and marks.

Refactored Bar Chart

This bar chart displays population estimates for ten countries from the United Nations’ 2019 dataset. Built with React and D3 v5, it uses scaleBand and scaleLinear to map country names to the y-axis and population values to the x-axis, rendering SVG rectangles via the Marks component. Axes are generated through custom AxisBottom and AxisLeft components, which leverage scale ticks and domains to produce labels and gridlines.

Refactored Bar Chart

A bar chart displays the 2020 population estimates for the top 10 countries, sorted by country name along the vertical axis and population magnitude along the horizontal axis. Built with React and D3 v5, the visualization uses `scaleBand` and `scaleLinear` for positioning, with SVG rectangles rendered by a custom `Marks` component. Axis components generate tick marks and labels using `xScale.ticks()` and `yScale.domain()`. Data is loaded asynchronously via `csv()` from a UN population dataset hosted on GitHub.
