This visualization shows the top 15 countries with the highest number of confirmed COVID-19 cases using horizontal bar charts. The bars represent case counts with a linear scale on the x-axis and country names on the y-axis. The code loads data from a CSV file hosted on GitHub and uses React’s useEffect hook to fetch and parse the data asynchronously. D3’s scaleBand and scaleLinear functions map the data to SVG rectangles, while d3.csv handles the data import. The chart is embedded within a React component that renders the SVG output directly.

AI-generated description

Boilerplate code for a React + D3 visualization with:

CDN links for React, ReactDOM, and D3
Basic React boilerplate
Variables for dimensions and margins
A VizContainer component that:
- Abstracts SVG/group container elements
- Follows the margin convention
- Show the margins, which can be easily removed by deleting the showMargins={true} prop

Top 25 Countries with confirmed covid cases

This horizontal bar chart ranks the top 25 countries by confirmed COVID-19 cases, using a linear x-scale and band y-scale. It loads CSV data via `d3.csv`, slices the first 25 rows, and renders SVG rectangles with `d3.scaleBand` and `d3.scaleLinear`. Axes are manually drawn using `xScale.ticks()` and `yScale.domain()`, with blue gridlines. Built with React and D3 v6, the visualization uses a fixed 960×500 viewport and margin convention.

Untitled

This visualization displays a horizontal bar chart of the top 20 countries by COVID-19 case counts, using data from a CSV file loaded via d3.csv. The chart maps country names on a d3.scaleBand y-axis and case numbers on a d3.scaleLinear x-axis, with blue bars and gridlines rendered as SVG elements. The React component fetches the data asynchronously, parses numeric values, and uses d3’s max function to set the x-domain, while y-axis labels and ticks are manually positioned using SVG text and line elements.

COVID19 Cases TOP 10 countries-March 19

This visualization displays the total reported COVID-19 cases for the top ten affected countries as of March 19, using a horizontal bar chart. The chart encodes case counts as bar lengths along a linear scale, while country names are arranged on a band scale. Data is loaded from a local CSV file using `d3.csv`. The SVG rendering is built with the D3 v5 API, specifically `select`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom`, with axis tick labels formatted using `format('.2s')`.

ICE-6_11590101

This visualization displays the top 10 countries by total COVID-19 cases as a horizontal bar chart, with country names on the y-axis and case counts on the x-axis. The bars are rendered as SVG rectangles using React and D3 v5, with scales created via `d3.scaleBand` and `d3.scaleLinear`. Data is loaded asynchronously from a CSV file using `d3.csv`, and axes are drawn manually with gridlines and tick labels. The title indicates the chart focuses on the highest COVID-19 case counts among nations.

This example presents a horizontal bar chart that displays the top 20 countries by reported COVID-19 cases, based on data from a CSV file loaded via `d3.csv`. The visualization uses React to manage component state and render an SVG, with D3 v5 scales (`scaleBand` and `scaleLinear`) to map country names and case counts to pixel positions. Each rectangle’s width encodes the case count, and the chart includes a blue gridline for the x-axis ticks.

Top 10 Countries by COVID-19 Cases Bar Chart

This bar chart displays the top 10 countries by total COVID-19 cases, with each bar’s height representing the case count and the country name labeled on the x-axis. The visualization uses d3.csv to load data from a GitHub gist and d3.scaleBand for positioning bars, while d3.scaleLinear maps the case values to the y-axis. Hovering over a bar changes its fill color to orange, implemented through d3 selection event handlers. Axes and labels are generated using the @curran/axis-labels library alongside d3.axisLeft.

Top countries of Covid-19 Bar Chart

This example displays a bar chart of the top ten countries by total COVID-19 cases, ranked by population. It uses D3's `scaleBand`, `scaleLinear`, `axisLeft`, `axisBottom`, and `line` APIs to render the axes and a line mark. The visualization loads data from a remote CSV via `csv()`, sorts it, and slices the top ten entries. Local ES6 modules like `@curran/axis-labels` handle axis labels, while `select` and `join` manage SVG elements.

bar graph

This bar graph displays the total number of COVID-19 cases for twelve countries, ranked along a horizontal axis with country names on the vertical axis. The chart uses the D3 library (v6) with an SVG rendering approach in a React framework. It employs `scaleLinear` and `scaleBand` for the scales, `axisBottom` and `axisLeft` for the axes, and loads data from a CSV file. The bars are colored pink via CSS.
