Your chart conveniently stops before listing Uruguay, Paraguay, Mexico, Costa Rica, Southj Africa, Philippines, Panama, Colombia, Brazil, Venezuela, El Salvador, Guatemala, Jamaica, Eswatini, and Honduras.
Starting at South Africa - their per-capita gun murder rate is double the USA, Panama is triple, Colombia is almost 5 times our rate, Venezuela is more than 6 times, Guatemala 7x, Eswatini over 8x, Honduras - wow, 16x the gun murder rate as the USA.
Your chart is just another attempt to demonize US gun owners by ignoring the fact that we're closer to the bottom of the list than the top. Whoever made that chart thought you would be too lazy (or stupid) to figure out they were lying to you, and they were right.
Here's what the real chart looks like, with no data omitted:
