April 30 — Mobile Improvements
Greatly improved mobile display including axis labels, country text placement, and more.
Fixed “saved links” for daily and weekly averaged cases.
Changed default “Show” to 25 countries to reduce rendering time on phones/tablets. Custom links can be bookmarked to show all, 50, etc.
April 24 — Hospitalizations and COVID-19 Tests for US States
Added four new “Data” selection for US states: “Hospitalized Cases”, “Total COVID-19 Tests”, “New Tests /Day”, “New Tests, 1 Wk. Avg.”.
The data from Johns Hopkins starts on Apr. 12, so the total graphs are a little uninteresting right now. However, I believe the trends will become interesting over time and the daily tests already show useful insights.
FIX: Fixed link to normalized charts.
UI Improvement: No longer displays a message of “(None)” having nothing to highlight.
April 21
1/3/7-day trendline is drawn for only seven days forward, not forever, to avoid extreme extrapolation.
April 20
Upon changing any default values, a URL now appears below the graph with your saved options.
Bookmark or share the URL to go directly to the graph with your chosen options.
April 17
Minor UI Enhancement: First “Highlight” option is now “(None)” to highlight no country/state.
UI Fix: Country/state labels were incorrect positioned on the newly added average graphs if the most recent raw data value was 0 (eg: 0 new deaths). Fixed and now appears correctly positioned.
April 16 — One Week Average Cases/Deaths
Added two new “Data” options: “New Cases /Day, 1 Week Average” and “New Deaths /Day, 1 Week Average”.
Both options show a 7-day trailing average of the new daily cases/deaths, with detailed tap/mouseovers showing the the actual cases data and the trailing average data.
April 15 — Overview Page
Added an “Overview” page documenting how the visualization was created, the motivations, and other bits.
Handled countries with no data gracefully and included message below graph when nothing is available to highlight.
Sorting on normalized “Top 10” / “Top 50” is now based on normalized data.
April 13
Added “Show” option “Top 10” to show only the 10 countries/states with the largest values.
The “New {Cases|Deaths} /Day” now is based on the same start date as the “{Confirmed Cases|Deaths}” instead of being based on a /Day threshold.
Data points that are zero or negative are now rendered a data point below the x-axis when a country is highlighted to allow tap/mouseover interaction with the data. (Line charts still do not connect these points that are outside of the grid.)
April 12 – Multiple Highlights
New UI “Add Additional Highlight” to allow highlighting any number of countries!
Changed default trendline to only show the original 35% trendline.
April 11 – “Highlight Only” View (and Mobile Improvements)
The “Show” UI options has been redesigned, allowing you to “Show: Highlight Only” to view only one country.
All countries in the dataset are now listed in “Highlight” and the “Show” will move to “All” if needed when in “Top 50” view.
Several layout improvements specifically to remove some text overlap on mobile.
April 10 – Dynamic Trendlines
Added logic to create dynamic trendlines from a highlighted country, allowing a visual indication of future progress at current growth rates.
Added new UI option “Trendline” to show the trend of the currently highlighted country.
By default, the original 35% trendline and a 1-week trend for the highlighted country are now displayed.
Redesign of trendline label positioning.
Various other minor UI tweaks to clean up the visualization with the display of trendlends.
Minor UI Improvement: In the normalized data charts the default scale was based off the largest value in the dataset before the data was filtered. Now, the default view is based off only the data displayed.
April 9 – Axis Zoom
Changed the default (full) from being the next power of 10 to being 1.2x the maximum value.
Add new UI option “Y-Axis” allowing you to switch between the default (full) scale and a scale focused on your highlighted country/state.
