# the script looks in your /var/www/data/ directory
# it will look for csv files of the same name of the directory and name your graph the same name as your directory
# It skips the "Sample Data", ".gitignore" ,"profiles" and "My First BrewPi Run" directories
# it will print out the name of the graph/directory and the URL when it is done
