Bar Chart

This bar chart shows total COVID-19 cases for 14 countries, with values labeled above each bar. It uses d3.scaleBand for the x-axis, d3.scaleLinear for the y-axis, and d3.axisBottom/d3.axisLeft to render the axes. Bars are drawn as SVG rectangles with a steelblue fill, and case numbers are formatted with toLocaleString. The chart includes a title and uses the d3.selectAll pattern to bind data to elements.

Trabajo Final Covid19

This bar chart displays confirmed COVID-19 case counts for ten countries, with the United States leading at over one million cases. The visualization uses D3 v5’s `scaleLinear` and `scaleBand` to map case numbers to horizontal bars and country names to vertical positions, rendering as SVG. Axes are generated with `axisBottom` and `axisLeft`, with tick formatting via `format('.3s')`. Data is loaded from a CSV file, and styling is applied through external CSS, including green-filled rectangles and custom title labels.

Bar Chart

This bar chart visualizes confirmed COVID-19 cases by country and region from the Novel Corona Virus 2019 dataset on Kaggle. It shows the total confirmed count for each location using horizontal bars, with country names on the y-axis and case numbers on the x-axis. The visualization is rendered as an SVG using D3 v5, leveraging `d3.csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to map the data. The chart displays only the first two dates from the dataset, as the code parses observation dates without filtering.

covid-19 bar chart

This bar chart displays total COVID-19 case counts for different countries, with bars colored using a categorical palette and labeled with case numbers. It shows tooltips on hover containing country and total case information. The visualization uses D3 v7 to build the SVG, employing `d3.scaleBand` and `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.schemeCategory10` for bar colors. The underlying data is embedded directly in the source code.

Bar chart - covid19

This bar chart displays the total number of Covid-19 cases in the top five US states as of January 12, 2021, sourced from Worldometer. The visualization uses d3.csv to load the data and d3.scaleLinear, d3.scaleBand, and d3.axisBottom/axisLeft APIs to map case counts to bar lengths and states to vertical bands. Each state’s bar is rendered as an SVG rect with a green fill, while the horizontal and vertical axes provide numerical and categorical reference points. The chart is built with D3 v6 and renders entirely as SVG elements.

Making bar chart

A horizontal bar chart displays COVID-19 case counts per country, with bars ordered by the data’s CSV order. The visualization uses D3 v5’s `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and `axisLeft`/`axisBottom` for gridlines. Data is loaded via `d3.csv` and rendered as SVG rectangles with a steelblue fill, while a clickable “Hello” button triggers a browser alert.

HTML Starter

This example demonstrates a bar chart visualization of COVID-19 data, showing confirmed cases, recoveries, and deaths across multiple countries on a specific date. The chart uses the D3.js library, specifically `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with SVG rendering for the bars. The data is loaded from a CSV file containing country-level pandemic statistics. The visualization includes axes with labels and interactive mouseover/mouseout events, though the actual data displayed focuses on the initial case counts from January 2020.

Covid-19 Data Visualization

This visualization displays total COVID-19 case counts for fourteen countries using a bar chart. Each bar’s height and value labels are mapped through d3.scaleBand and d3.scaleLinear, while d3.axisBottom and d3.axisLeft render the axes. Tooltips appear via mouseover events, and the SVG rendering includes a title and case number annotations. The data is embedded in the code as a static array, with cases formatted using the toLocaleString method.
