This bar chart displays COVID-19 death counts by country, using rectangular bars sized proportionally to each nation’s reported deaths. The code loads data from `deaths.csv` via `d3.csv`, then uses D3’s selection methods (`selectAll`, `data`, `enter`) to append SVG `rect` elements and `text` labels. Bar heights are scaled against the maximum death value, with labels positioned at each bar’s base. The visualization reads a local CSV file and renders entirely as SVG, with styling defined in an inline HTML stylesheet.

module manager uses local packages

Guidelines (un)named exports

Default exports give other name to imports. This can be confusing.
Best practice always use named exports.

presentation bar chart

This horizontal bar chart displays deaths per country, with each bar’s length proportional to the death count. The chart uses D3 v7’s `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft`/`axisBottom` for the axes. Data is loaded from a CSV file via `d3.csv` and rendered as SVG rectangles. The computed values are multiplied by 1000, and bars are styled maroon with a 0.3 padding between bands.

Make a bar chat d3js

This example shows a simple bar chart of COVID-19 total cases by geographic region, using data from a local CSV file. The bar heights represent case counts, with regions listed along the y-axis. It uses d3.scaleLinear for the x-axis domain, d3.scaleBand for the categorical y-axis, and renders SVG rectangles via d3.selectAll and data joins. The code imports specific functions from D3 v7 and the CSV loading is handled with d3.csv.

Bar graph of covid deaths

A bar chart displays COVID-19 deaths across selected countries for each day of May, with a slider to change the date. It uses D3 v5 scales (`scaleBand`, `scaleLinear`) with React for rendering SVG rectangles. Data comes from a CSV of COVID-19 statistics, filtered by location and day. The chart sorts countries by death count and uses native SVG `<title>` elements for hover tooltips.

Fork of Fork of Fork of ICE-6 bar graph

A bar chart displays the total COVID-19 deaths for twelve countries, forming a ranked comparison of mortality. The visualization loads CSV data from a GitHub gist and renders horizontal bars using React and D3 v5. Code uses `d3.csv`, `scaleBand`, and `scaleLinear` to map country names and death counts to SVG rectangles. Axis ticks and gridlines are drawn manually with `line` and `text` elements, while the chart title appears in the HTML heading.

bar viz for testing

This example visualizes death rates by year using a horizontal bar chart, with each bar’s length encoding the death count and the y-axis listing years. The chart is rendered as SVG using D3.js v5, primarily leveraging `d3.csv` to load data, `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisBottom`/`axisLeft` for tick generation. Data is sourced from a CSV file, and death values are multiplied by 1,000 before plotting. Styling is applied via CSS, setting bars to steelblue and customizing axis text.

Simple Bar Chart

This bar chart displays the number of deaths reported by countries in June 2021, filtered to values greater than 5,000 from the World Mortality Dataset. It uses D3.js v6 with SVG rendering, employing `scaleLinear` and `scaleBand` to map death counts and country names, along with `axisBottom` and `axisLeft` for the axes. The dataset is loaded via `d3.csv` from a GitHub Gist, and the chart resizes to the full browser window.

gw

This visualization shows the top 10 countries by cumulative COVID-19 deaths, using horizontal bars scaled by total deaths. It renders an SVG bar chart with d3.scaleLinear for the x-axis and d3.scaleBand for the y-axis, styled with custom CSS. The data comes from a CSV file sourced from Worldometers, and the chart includes a formatted x-axis with d3.format and labels for the chart title and axis. The code uses D3 v6 within a React framework.

ICE-6.js

This bar chart displays COVID-19 death counts by country, with a horizontal layout where each bar's length is proportional to the number of deaths. The visualization uses D3 v7’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to map the CSV data to an SVG canvas. A margin-based coordinate system positions the axes and cyan-filled rectangles, while the data is loaded via `d3.csv` and rendered as a static, non-interactive graphic.
