COVID-19 Dashboard Tracker Using AnyChart JS Charts for Interactive Data VisualizationData visualization has played an important role during the COVID-19 pandemic, allowing governments, scientists, healthcare professionals, and the general public to better understand different aspects of the crisis. There are many illuminating projects all over the web that leverage charts and maps to effectively communicate what the coronavirus statistics have to say. Some of them are using our data visualization tools under a free license provided as part of the special initiative we announced last spring to support the global COVID-19 data analysis effort.

We told you about two examples of such projects earlier: StopCorona and iConcepts SARS-CoV-2 Stats. Now let us introduce you to another interesting resource — COVID-19 Dashboard Tracker by Maxime des Touches. Launched more than a year ago, while Maxime was yet a computer science student, it has turned from a simple online data table into a complex interactive data visualization project offering up-to-date insight into how the pandemic unfolds in France and worldwide.

Maxime kindly agreed to talk to us about his COVID-19 tracker, experience using AnyChart, and the pandemic in general. Check out our quick interview, glance at a few screenshots, and try his open-source dashboard by yourself. (Stack: HTML/jQuery/JSON.)

We have no idea what it is and who it is, but this image is a part of Sally L. Steinberg Collection of Doughnut Ephemera of the Smithsonian Institution. You can read about the collection here and here. It includes a lot of nice pieces like this vintage donut-related infographic:

So, does the mysterious chart tell the truth? Has donut hole size really shrunk over the years? It seems that this question is of great public interest! It is thoroughly discussed in this article on Vox.com: Have donut holes gotten smaller? There is also a fierce discussion on Reddit, where one of the participants wisely notes that “1927 was a sad time to be alive”.

However, our customers should not worry: when you work with AnyChart JavaScript donut charts, you can easily configure the size of the hole! Visit our Gallery to see some samples of our donut charts.

With AnyChart, you can create highly customized interactive donut charts like this one:

This chart was used in our Investment Portfolio Dashboard – we wrote about it earlier: Investment Portfolio Dashboard by AnyChart Charting Framework.

Stay tuned, we have something to say about pie charts too!
