Using EquationMap for content entry

For the Physics Derivation Graph, I started out entering expressions manually into a plaintext file. I then graduated to manually entering expressions into a XML, then CSV file. Rendering was done in GraphViz and then d3js. In the past few months, I created an interactive terminal prompt for a more automated entry using Python, still rendering with d3js. I experimented with a web-based interface using Flask, but recognized I was slowly evolving towards the EquationMap interface for both display and entry.

Instead of re-inventing EquationMap, I realized I could use EquationMap as a front end. I would then export the graph .tex file and parse it into the Physics Derivation Graph. This benefits both EquationMap and the Physics Derivation Graph: EquationMap gets more traffic and more use cases, and PDG doesn't need to create a front-end.

Here's two different examples of using EquationMap with Inference Rules:

I like the second instance better.

Here's an example of completing the square without inference rules

and with inference rules

and generalized symbolically

I like the fact that I can easily refer to different iterations of the development

The ease of entering Latex and connecting nodes is very convenient!

The export function produces a combination of JSON and Latex.
I've written a parser for the .tex output from EquationMap
