 ## Introduction

 dependency visualizer (auto roadmap)
 
 `depviz` aggregates **tasks** from multiple projects and generates visual representations (graphs) of the dependencies.

 The ultimate goal of this tool is to allow the tech and the non-tech to collaborate seamlessly.
 
 Oftentimes, there are “non-technical project managers” that love tools like Jira and try to define everything, including the delay required.
-Developers, however, mostly hate Jira-like tools and prefer to focus on small tasks with a simple interface, like Trello, github issues, gitlab issues.
+Developers, however, mostly hate Jira-like tools and prefer to focus on small tasks with an easy-to-use interface, like Trello, GitHub issues, GitLab issues.
 
 The idea of depviz is to:
 
 * link those different tools (aggregate the different sources and find the relationships: find that this exact “Jira user story” belongs to those 5 technical issues on github
-* create various visual ways of displaying this information. Then, we can easily have a copmany that has some non-technical project manager only focusing on user stories and their priorities, and devs that focus on tasks and estimate the tasks by themselves (everyone doing what they are good at)
+* create various visual ways of displaying this information. Then, we can have a company that has some non-technical project manager only focusing on user stories and their priorities, and devs that focus on tasks and estimate the tasks by themselves (everyone doing what they are good at)
 * in general, help everyone have the overall vision more clear
 
 ## Target
 
-* Graphs are “fun” but not very useful yet, a good dependency tool would be like graphviz. The current depviz version makes the graph in something that is more “weight-based”, because nodes will be groupes to make the graph fit the screen. Graphviz is not focused on making things beautiful, but focused on being 100% clear on the dependency. We need a good graph driver that supports this kind of graph.

 * Having options for multiple layouts/graphs.
 * Implementing the [PERT method](https://en.wikipedia.org/wiki/Program_evaluation_and_review_technique) and adding more fields in depviz: due date, difficulty, etc, in order to create graphs for “finding the shortest path”, for example.
 * Improving the UI to improve collaboration (sharing a URL, etc).

 * a `Repository` is a `Depviz Owner` because even if you can archive a repository, it's not the normal lifecycle, and will most of the time be unrelated with the amount of tasks done
