@Edent Er, well I get this immediately
@mattround boooo!
It is a stupidly long-running script and I thought I could get away with running it on a free host.
Ah well, back to the drawing board.
@Edent Kept trying & got it to work eventually! In Chrome it appears gradually as I assume you intended, in Safari it seems to be loading behind the scenes and only renders when I stop it
@mattround interesting! I didn't realise Safari was so fastidious.
Cheers for letting me know.
