If you can't make heads or tails of the image then here's a wrap up of what it'll tell you:
One of the things I noticed when looking at this graph, is that the saying that when something is like Greek to you, then it's foreign, has merit! Greek is an old ass language that separated from the rest of the european languages very early. Matter of fact is, it's so old, it separated from the rest of the european languages before we separated from the hindu and iranian languages! Our languages has more in common with Persian, Hindi and Sanskrit (Hinduism's holy language, and also used in Buddhism) than they have with Greek. I was surprised at this and I'd be willing to bet a lot of others are.
Of the Italic languages, Latin is most unlike the other languages, having separated from the branch earlier than the rest.
The language Latin should share the most with (judging by when the two last shared a common "ancestor language") is Sardinian, something I can honestly say I did not know. It's also fairly closely related to Romanian. And Sardinian and Romanian are very closely related.
Other than this there's not all that many surprises in the italic language section, Italian is closely related to Sicillian and Corsican, and Spanish and Portugese are closely related. Catalan is more closely related to French than it is to Spanish, which might come to some peoples surprise. And also, if you've ever caught yourself thinking which language Italian is more closely related to, Spanish or French, the answer is that it technically should be Spanish, but because of all the proto-languages Spanish has gone through since then, it might actually share more in common with French linguistically. But hereditary, more closely related to Spanish, and Portugese, probably even more with Portugese actually.
And now on to the Germanic languages. The surviving languages can be grouped into Scandinavian, and West German. I've done some research and the forefather to all Germanic languages, the "Proto-Germanic" language is thought to have originated in southern Sweden. From there (or "here" I might say) it spread west into Norway and south into Denmark and Germany, from there it went west into Northern France, Netherlands and eventually Britain, it also went east into Poland but that branch of Germanic languages did not survived into present time. Like I think most people did I expected the Germanic languages to have originated from Germany. But appearantly the word "Germanic" has got nothing to do with the orign of the language, it has got soemthing to do with where Roman's first encountered speakers of a germanic language. The reason we say Germanic languages is because that's what Julius Ceasar called the people who spoke it. He was the first to group these barbarians living on the east side of the river Rhine and beyond with a unified name. Renaming it to "Swedic languages" or "Norsic languages" would be a mess, but it would be an accurate mess


Albanian has it's own language group, it separated from the Indo European language tree last. And could therefore be argued to be the most modern of the indoeuropean languages.
I didn't have time to write about the Celtic and Slavic language groups so if you want to understand their relations you have to read it yourself
