In the long term, we need something better. PETSc binary formats can't<br>
carry enough metadata to be usefully plottable without user interaction. I<br>
think I'm still in favor of a SQLite backend (for simplicity and<br>
versatility) indexing binary files written using MPI-IO. Most visualization<br>
and metadata tasks should be answerable in 1-line SQL queries instead of<br>
custom page-long graph traversals.<br>

Yes, but have a look at petscplot (<br>
<a href="https://github.com/jedbrown/petscplot/wiki/PETSc-Plot" target="_blank">https://github.com/jedbrown/petscplot/wiki/PETSc-Plot</a>) for some ideas on<br>
plotting. (petscplot parses plain ASCII output and creates a few plot<br>
styles, see <a href="https://github.com/jedbrown/tme-ice/blob/master/make.sh#L5" target="_blank">https://github.com/jedbrown/tme-ice/blob/master/make.sh#L5</a> for<br>
more example invokations.)<br>
