Answer 1

The best choice is to have a combined use of aspect ratio on normal definition of d3 graph's width and height. This has helped me in lot of my graph works.
Step 1 : Dynamically get the height of the div to which the graph has to be appended.
Step 2 : Declare width as aspect ratio with respect to the dynamically caught height.

var graph_div = document.getElementById(graph.divId);
graph.height = graph_div.clientHeight;
graph.width = (960/1200)*graph.height;
