code-to-tree

I have following hello world programs in 7 different languages: C: ``` #include <stdio.h> int main() { printf ("Hello!\n"); return 0; } ``` C++: ``` #include <iostream> int main() { std::cout << "Hello!" << std::endl; return 0; } ``` Rust: ``` fn main() { println!("Hello!"); } ``` Go: ``` package main import "fmt" func main() { fmt.Println("Hello!") } ``` Ruby: ``` puts "Hello!" ``` Python: ``` print(R"""Hello!""") ``` Java: ``` public class HelloWorld { public static void main(String[] args) { System.out.println("Hello!"); } } ``` Can you generate tree-like, colorful structures for their AST, and put each of them in one SVG? I suggest you embed those SVGs into one HTML, so that the layout could be easily managed. And don't forget node's text should be clearly displayed.
