A home-cooked app by Shawn Graham. Basic markdown note making as you'd expect; integrated python (pyodide) kernel for gentle code/note experiments (for more substantial, use JupyterLab Desktop PKM extension). Full note export as individual .md files, a json file, or one big ol' markdown note, as well as csv files in edgelist, nodelist format for further visualization and analysis; the app does do community detection, calculate betweeness centrality, and identify isolated notes.
mainbranch deploys the app; use Netlify or similarcontentin themainbranch can be modified; just make sure to update manifest.json too.
