TheBrain10 .json (File>Export>JSON Files ) to .dot visualization with Graphviz

• Python 3 support
• UTF-8 support
• Nodes (thoughts.json)
  • support shapes, colors
  • size depends on PageRank centrality
• Links (links.json)
  • support types, directions, colors
• Layout
  • support layout (algorithm), splines

API

Example: see test/test.py

brain_json2dot(thoughts_path, links_path, dot_path='thebrain.dot', png_path='thebrain.png', 
                layout='dot', bg_color='grey22', node_shape='circle', node_color='white', 
                edge_default_color='white', edge_splines='', edge_font_size=10)

• Useful reference for parameter customization: Node, Edge and Graph Attributes in Graphviz
• The function will output both .dot file + .png file
• Recommended tool for .dot: MS Code + Graphviz Interactive Preview

TODO

• Doc: parsing of thebrain10's thoughts.json & links.json
• Doc: Windows / Mac installation
• Dev: SVG
• Dev: publish package to PYPI
• Dev: correct color mapping (thebrain exported json seems to have bugs about color)
• Layout: label / tag
• Layout: parent / sibling location restriction in visualization
• Layout: community detection
