This scatter plot visualizes COVID-19 vaccination rates and reported case counts over time, using a dual y-axis to compare the two metrics. The chart demonstrates a reduction in cases as vaccination increases, with blue circles representing vaccination proportions and gray circles showing seven-day average case counts. The visualization uses D3 v6 with `scaleTime`, `scaleLinear`, `d3.axisLeft`, `d3.axisRight`, and `selection.join` for animated circle updates. Data comes from Our World in Data and the New York Times rolling averages, rendered as SVG elements with CSS-styled axes.

AI-generated description

A demonstration of how to start using D3 version 6.

COVID-19 vaccination rates in blue versus reported cases in gray.

Data are from CDC COVID-19 US population vaccination counts as proportions of the US population size and the NYT COVID-19 infection 7-day trailing average cases counts for the US population using a dual y-axis for the two public use data sets.

Fork of Scatter Plot COVID-19 Vaccination and Cases with Dual Axis

This visualization displays the relationship between COVID-19 vaccination rates and 7-day average case counts in the United States using a dual-axis scatter plot. Steel-blue circles represent the proportion of the US population vaccinated, while gray circles show infection counts, with animations transitioning the radius and positions of points. The chart annotates the maximum vaccination percentage and case count reduction over time. Built with D3 v6, it utilizes `scaleTime`, `scaleLinear`, axis components, and `selection.join` for data binding, drawing from Our World in Data and NYT rolling averages datasets.

Fork of Scatter Plot COVID-19 Vaccination and Cases with Dual Axis

This interactive scatter plot visualizes COVID-19 vaccination rates (in blue) against reported case counts (in gray) for the US population, using a dual y-axis. The visualization animates data points over time using D3 v6 and SVG, with vaccination data from Our World in Data and case data from the NYT. Users can toggle between partial and fully vaccinated metrics via a custom menu. The code employs D3 scales, axes, transitions, and the `selection.join` pattern for reusable chart components.

Scatter Plot COVID-19 Vaccination and Cases with Dual Axis

This interactive scatter plot shows COVID-19 vaccination rates in blue against reported cases in gray, using a dual y-axis to compare the two disparate data scales. The chart includes a dropdown menu to toggle between partially and fully vaccinated populations, with annotations highlighting key milestones. Built with D3 v6, it uses `scaleTime`, `scaleLinear`, `axisLeft`, `axisRight`, and `selection.join` for enter/update/exit circle transitions, rendering SVG with animated growth on load. Vaccination data comes from Our World in Data, while case counts are sourced from NYT rolling averages.

Scatter Plot COVID-19 Vaccination and Cases with Dual Axis

This interactive dual-axis scatter plot visualizes the relationship between COVID-19 vaccination rates (blue circles) and reported cases (gray circles) in the United States over time, using D3 version 6 with SVG rendering and animated transitions. It draws on CDC vaccination data and NYT rolling averages, scaling vaccination proportions against raw case counts with separate y-axes. The visualization includes a dropdown menu to toggle between partially and fully vaccinated metrics, and uses D3’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, `axisRight`, and selection joins with transitions for the animation.

Scatter Plot COVID-19 Vaccination and Cases with Dual Axis

This scatter plot shows the relationship between COVID-19 vaccination rates in blue and reported case counts in gray for the US population, with a dual y-axis for the two metrics. An interactive menu lets viewers toggle between partially and fully vaccinated proportions. The visualization uses D3 v6 with the `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `axisRight` APIs, and animates circle positioning via `transition` and `selection.join`. Data comes from the CDC and NYT rolling averages, with vaccination values normalized by US population size.

Fork of Scatter Plot Vaccination and Cases

This scatter plot visualizes the relationship between COVID-19 vaccination rates and infection cases in the United States over time. It overlays two datasets—vaccination percentages from Our World in Data and case counts from the New York Times—on a shared date axis, with annotations highlighting the final date's progress. The visualization uses D3.js v6, specifically `scaleTime`, `scaleLinear`, `selection.join` for animated circle transitions, and `d3-annotation` for labels. SVG rendering animates circles growing from zero radius while a dropdown menu allows switching between partial and fully vaccinated metrics.

Scatter Plot COVID-19 Vaccination and Cases with Dual Axis - TN

This scatter plot animates COVID-19 vaccination rates and 7-day average case counts for the US population, using a dual y-axis where steelblue circles represent the proportion of people vaccinated and gray circles represent case counts. The visualization demonstrates that as vaccination numbers rise, case numbers decline, with annotations highlighting the peak and final case counts. Built with D3.js (version 6.7.0), it implements reusable scatter plot patterns with custom scales for time and linear axes, animated circle growth, and interactive menu selection for toggling between partial and fully vaccinated data. The code leverages D3's data joins, transitions, and annotation APIs, pulling data from Our World in Data and the New York Times rolling averages dataset.

Covid-19 Cases

This visualization tracks COVID-19 cases and vaccination rates in the United States using a dual-axis scatter plot. Blue circles represent the proportion of the population vaccinated (partial or full), while gray circles show the seven-day average of new cases. The animation reveals trends over time, with annotations highlighting key milestones. Data comes from Our World in Data and the New York Times, rendered with D3 v7 (d3.scaleTime, d3.scaleLinear, d3.axisBottom, d3.axisLeft, d3.axisRight) and d3-svg-annotation. A menu lets users toggle between partial and fully vaccinated metrics.
