BI (“Business Intelligence”) dashboards with data used to be a corporate thing. Firms such as my previous employer McKinsey would advice clients what metrics to put on them, and how to display them. This is tricky, there is an infinite amount of data to choose from, and even more options to slide and dice the figures.
The COVID outbreak has created many country-wide public dashboard with data. In Israel where I am based, a large tribe of “amateur” statisticians has emerged that runs and discusses analyses on Twitter. The other dashboard I had a look at is the Dutch one (part of my family still lives there).
- Dutch board
- Israeli board (use the translate option that is offered by the Google Chrome browser)
The approaches are different, and I prefer the Israeli one.
- The Dutch board looks very pretty, has lots of explanations in text, and has useful maps of regions with color coding. The problem is that it stretches out over many, many, pages, and priotises static data over time series.
- The Israeli one is just one page, with lots of time series graphs, so you can see things develop over time. And not for basic statistics such as overall cases, benchmarks can get very specific. Benchmarks are normalised so you compare apples with apples (i.e., cases / 100,000 by vaccination status). Also, government policy and benchmarks are tightly integrated. The government wants to encourage parents to vaccinate children, so there are statistics specifically aimed at that target segment. Another example: after discussions whether to close the airport or not, stats about airport tests were published (split by country, so citizens can make the call to travel somewhere or not based on their personal risk appetite).
The biggest advantage of the all-on-one-page approach is that people start to understand it, and come back to it very often to get the latest data, even venting anger when it is not updated on a day.
Data visualisation to involve the public in decision making and/or influence day to day behavior.

PS. Israel does a PCR test for every single arrival at its airport, so the arrival statistics on the Israeli dashboard are probably one of the best global indicators of what is going on in a particular country.
