In this visualization (https://www.bbc.com/portuguese/internacional-51718755), released by the BBC, the map shows different circle sizes to show confirmed coronavirus cases per country. It allows the reader to notice where the worse scenarios are. The visualization achieves "the overall goal to communicate the message". It is also direct when doing this. I think, however, that using a single colour to frame the situation was not the best choice here. "Contrast color or increase saturation to highlight certain parts of the graphic", as suggested in “Deconstructing Data Viz” reading as a possibility would have a much more compelling effect, in my opinion, to reinforce the different status of the spread of the virus among the countries. The infographic title is enough clear, but is not impactful.
