Using gpuplot instead of opencv?

[mjyc]

While working on https://github.com/onlytailei/CppRobotics/pulls I noticed OpenCV installation takes long time and looked into where & how opencv was being used. Seems like it's mostly for plotting purposes and I was wondering if you considered using a much smaller library focusing on plotting, e.g., http://stahlke.org/dan/gnuplot-iostream/ ?

Gnuplot is very lightweight solution. we can use FILE *gnuplotPipe = popen("gnuplot -persist", "w"); then we send data points in a for loop with some small sleep.
