I’ve got a couple of questions concerning some SVG images that are embedded in this chord diagram:
The nodes in the diagram correspond to teams in the Big Ten conference and each one is labeled by a team logo. Those logos are SVG images that come from Wikipedia who claims that the images are in the public domain. After I built this and gave a it a bit of thought, it seems a bit hard to believe that those images would be in the public domain.
Question 1: Should I be concerned about the use of those images from a licensing perspective? More importantly, is that use something that the Observable team would be concerned about?
Question 2: The images don’t live here on Observable but, rather, they are linked from Wikipedia via an
image/xlink:href attribute. Assuming I have confidence that those links aren’t going anywhere, is there any technical reason that I should not link to images offsite like that?
