Code ta thik mone hocche. Problem hote pare generateOrganicPath function e jodi distance zero hoy tahole NaN hobe. Fix korchi:

Also check the 2d page:

Page thik ache. Let me check mindmap-data loading function:

Function ache. Add some debug log to see what's happening:

Fixed - zero distance case handle korlam path generation e jate NaN na hoy. Debug logs add korlam loading check korar jonno. Ekhon /2d route e gele preview dekhte para uchit.
