graphviz 출력 포맷

graphviz에서 neato를 통해서 이미지로 변환이 가능한데, 예제는 다음과 같다.

$ neato -Tpng -O test.dot

$ neato --help neato: option -- unrecognized Usage: neato [-Vv?] [-(GNE)name=val] [-(KTlso)<val>] <dot files> (additional options for neato)    [-x] [-n<v>] (additional options for fdp)      [-L(gO)] [-L(nUCT)<val>] (additional options for memtest)  [-m] (additional options for config)  [-cv]  -V          - Print version and exit  -v          - Enable verbose mode  -Gname=val  - Set graph attribute 'name' to 'val'  -Nname=val  - Set node attribute 'name' to 'val'  -Ename=val  - Set edge attribute 'name' to 'val'  -Tv         - Set output format to 'v'  -Kv         - Set layout engine to 'v' (overrides default based on command name)  -lv         - Use external library 'v'  -ofile      - Write output to 'file'  -O          - Automatically generate an output filename based on the input filename with a .'format' appended. (Causes all -ofile options to be ignored.)  -P          - Internally generate a graph of the current plugins.  -q[l]       - Set level of message suppression (=1)  -s[v]       - Scale input by 'v' (=72)  -y          - Invert y coordinate in output  -n[v]       - No layout mode 'v' (=1)  -x          - Reduce graph  -Lg         - Don't use grid  -LO         - Use old attractive force  -Ln<i>      - Set number of iterations to i  -LU<i>      - Set unscaled factor to i  -LC<v>      - Set overlap expansion factor to v  -LT[*]<v>   - Set temperature (temperature factor) to v  -m          - Memory test (Observe no growth with top. Kill when done.)  -c          - Configure plugins (Writes $prefix/lib/graphviz/config                with available plugin information.  Needs write privilege.)  -v          - Enable verbose mode

심심해서(?) svg로도 출력을 해보니 잘 나오는데, UNIX 문서로 되어있는지 메모장으로는 깨져 보인다.
(SVG는 원래 XML 과 같은 Markup이니 메모장으로도 보임)
