I’m sorry if that’s harsh, but my feedback would be: drop that chart!
It’s daunting, it’s going to freak out many newbies. Too much choice kills the choice.
You have one “default” at the bottom, Mint, so stick to that. Tell the newbies they can switch anytime to something else once they’re a bit more comfortable with the Linux-world. And if I’m not mistaken, you can install and try the main DEs with Mint also. Or you can recommend Ubuntu, or any other newbie friendly distro. Just pick one and don’t lose them over what they could see as an important difficult decision before they even get started.
