(Sorry if this is the wrong place to ask)
Is there a website akin to phpSyntaxTree / jsSyntaxTree that would allow me to manually type in something like bracket notation to make parse trees for Dependency Grammar? I can't seem to find anything on the internet for something like that. On UD's website, they mention a lot of tools that they use, but all of them seem to require some third-party application that I have no idea how to use, like Python. One of the tools mentioned was brat, and I've tried downloading it with Java and with Python installed on the computer, but I keep getting error messages when I try to run the program and it won't load or open properly. I've tried looking for tutorials on YouTube, but the best I got was this video. The website the person's using in the video most resembles what I'm looking for. I tried going to the very website they were using, but it seems like it's something that only the owner can edit? Outside of that website, I've not been able to find a single equivalent. I was thinking of using LaTeX since I saw something about a TikZ package that can allow one to make DG trees, but the installation process of LaTeX is really complicated, not to mention the "coding" (?) process. To clarify, I'm not looking for automated parse tree generators like CoreNLP or Stanza.
Edit: I've found a weird glitch? I don't know if it was intentional or not, but on UD's website, on page "Other Constructions", for some reason I'm able to edit example box 10 and 11... and the editing feature is exactly what I'm looking for: something "manual". This seems like some glitch because you're not supposed to be able to edit examples on a website, right? ...Is there an official website for this that they have or something?
