Sigma Layout does not fit in Container Window??

http://localhost/sigma.js/br-examples/d-index-old-aug22.html

Following a previous blog post:

http://raptorlicious.blogspot.com/2017/08/debugging-window-thing-in-sigmajs.html

document.getElementById('graph-container').offsetWidth   == 821

document.getElementById('graph-container').clientWidth   == 811 (want?)



document.getElementById('graph-container').offSetHeight == 256

document.getElementById('graph-container').clientHeight == 247 (want?)


Previously, in D3 I fit the container by:

var height = document.getElementById('graphcontainer').clientHeight - 4 

* document.getElementById('graphcontainer').clientTop;

 var width = document.getElementById('graphcontainer').clientWidth - 2 

* document.getElementById('graphcontainer').clientLeft;

++++++++++++++++++++++++++++++++++++

Do not worry about layout for now. You can fix this and the buttons later. For now look at

preparing the data for sigma.js instead of D3.
