Nit: TALA could be another layout engine for graphviz but its not a format itself (I suggested this in comments above). Graphviz also doesn’t imply specific layout unless you mean “dot” that is default. So conversion is somewhat undefined. Maybe you mean graphviz language to d2, afaik there is no official, 100% loss-less automatic translator because of some subtle differences in these declarative languages
