* Run @fc = 0

* make a list of all the objects/shapes that are present - make a list of the objects using data.json

|

*Caveats
|

- if there is already a circle, we can actually update the values on the same one if there is the SAME number of circles.

-else we can update the SAME ones and add the rest
