The excellent David McCandless has taken on the task of illustrating Covid-19 data in a very colourful and interactive way. He is author of the "Information is Beautiful" text book that is on our Reading List for the Higher Diploma in Data Analytics at NCI. While the source of the data (Johns Hopkins) is the same as that used by many other web sites (eg, The Irish Times Dashboard), McCandless's visualizations far outstrip others I have seen. the use of colour, shape, variety of charts, interactivity shows how big Data can be displayed in an interesting and effective way. Here's one of the best:

Choosing the right colours and shapes is an art, but it can be learned. You have to take into account the semantics of colour, what it is that you want to show, and how viewers will interact with your visualization. McCandless shows how far this can be taken to produce some wonderful visualizations - be sure to check them out.
