How to use

Apply tools in order (Python 3 required):

1. go tool nm -size <binary file> | c++filt and redirect to some file, e.g. symtab.txt

   (provided with the Go toolchain.)

2. python3 tab2pydic.py on the previously generated file, redirect to e.g. out.py

3. python3 simplify.py on the previously generated file, redirect to data.js specifically

4. python3 -m http.server

5. open browser on http://localhost:8000/treemap_v3.html

Included example data using CockroachDB

1. python3 -m http.server

2. open browser on http://localhost:8000/cockroach_sizes.html

Origin of the D3 viz source code

This repo uses D3 visualization code inspired from / modifying the following sources:

• Jacques Jahnichen's zoomable treemap at http://bl.ocks.org/JacquesJahnichen/42afd0cde7cbf72ecb81

• ported to D3 v4 by Guglielmo Celata at http://bl.ocks.org/guglielmo/16d880a6615da7f502116220cb551498
