fdp: Render a `png` image with a filename based on the input filename and output format (uppercase -O).

$ fdp -T png -O ${path-to-input-gv}

try on your machine

This command is using the "fdp" program to generate a visualization of a graph described in Graphviz DOT format.

Here is a breakdown of the different components of the command:

"fdp": This is the name of the program that will be executed. "fdp" stands for "Force-directed Placement", which is a graph drawing algorithm provided by Graphviz.
"-T png": Specifies the desired output format for the generated visualization. In this case, it is set to "png", which means the output file will be in PNG image format. Graphviz supports multiple output formats like PNG, SVG, PDF, etc.
"-O": This option is used to specify the output file name. In the command shown, "${path-to-input-gv}" is a placeholder for the actual path to the input DOT file, and the generated PNG image will be saved using the same name as the input file. The "-O" option is followed by the name of the output file, which will be the input file name appended with the ".png" extension.

PUTTING IT ALL TOGETHER: So, when you run this command by replacing "${path-to-input-gv}" with the actual path to your input DOT file, it will execute the "fdp" program with the input file, generate a force-directed graph layout, and save it as a PNG image with the same name (but with ".png" appended) in the same directory as the input file.
