GraphViz | Simple library to automatically visualize graph structures | Data Visualization library

I try to make png from decision tree that i made before from a data. Using package pydotplus, I want to save the png in my local storage and show it. It work in google colab, but it error in jupyter. It said

GraphViz's executables not found

This is my code

I am trying to install conda on EMR and below is my bootstrap script, it looks like conda is getting installed but it is not getting added to environment variable. When I manually update the $PATH variable on EMR master node, it can identify conda. I want to use conda on Zeppelin.

I also tried adding condig into configuration like below while launching my EMR instance however I still get the below mentioned error.

Suppose I have the GraphViz graph:

I'm just trying to get a DOT diagram to render. I have followed the documentation (https://github.com/magjac/d3-graphviz) to add the package and use it but when I try to run the application and access the DOT diagram, nothing renders and the the following error is thrown:

ERROR TypeError: Cannot read property '__graphviz__' of null. console error message

The app is an Angular 12 project here is the dependency list that is used

I'm using graphviz to visualize an AST tree in a compiler project I'm doing but a big problem with this is that the trees can get quite large, with some nodes having a lot of children. What this causes to happen is some parent nodes will be hugely separated from their parents, because their children force them to.

It looks like this:

My question is, is it possible to make it so that all nodes with only one child stay directly above the node below it? So, the "decl f" node will be right above the "assignment" node, while that assignment node stays directly above the "additive" node.

I tried to do this with invisible edges and strong weights between, say in this case, the "decl f" and "additive" nodes, but that ends up offsetting the "assignment" node so it doesnt collide with the invisible edge.

The code is automatically generated, but I'll still put the output here. This output is for this graph:

I'm using Jupyter Notebook to do graph analysis. I need to use Networkx to generate MultiDiGraph, I need to plot it as a tree, but there is an error occurring :

I want to use GraphViz as a C library(cgraph) but I don't know how to actually "import" it.
The folder contains makefile.am, so I should use automake to get a makefile.in file. Where do I go from there?

I'm really confused on the actual procedure to follow.

How to change colors in decision tree plot using sklearn.tree.plot_tree without using graphviz as in this question: Changing colors for decision tree plot created using export graphviz?

I'd like to use graphviz to produce a graph like this one:

How can I write such a graph?

So far, I've tried:
