Have come up with a neater version

Awk='BEGIN \
{
printf ("width: terminal %d\n", width);
stars = sprintf ("%200s", "");
printf ("stars: %s\n", stars);
gsub (".", "*", stars);
}
{ printf ("%.*s\n", $1, stars); }'

printf '%s\n' 4 1 0 3.75 17 |
awk -v width="$( tput cols )" "${Awk}"

I can capture the width of the terminal and pass it into an awk variable, make 
a long array of characters in awk and print a clipped section.

Also need to add auto-scaling to use the width of the terminal, using the 
largest the largest vales, and output the graph in an END block.
