Multiple dice games

README.md

A simple example where we run multiple dice games, illustrating how modularity and subgraphs are helpful

main.juttle

sub dice_rolls(n) {
    function roll() {
         return Math.ceil(6 * Math.random());
    }
    function toss_dice() {
         return roll() + roll();
    }
    emitter -limit n -start 0 | put throw = toss_dice()
}
 
sub frequency_table(total, field) {
    reduce total=count() by field | sort field
}
 
sub histogram(title, what) {
    frequency_table -total 'total' -field what |
        @barchart -title title -categoryField what -valueField 'total'
}

sub throw_dice(n) {
	const title = String.concat("Dice Rolls - ", Number.toString(n));
	dice_rolls -n n | histogram -title title -what 'throw'
}

// try it a bunch of different runs
throw_dice -n 10 ;
throw_dice -n 100 ;
throw_dice -n 1000 ;
throw_dice -n 10000
