Hi.
I have experience creating d3js charts. It sounds like the width / height are not being properly adjusted for the svg element.
I can fix this if you give me access to the underlying code (same goes for displaying an image on the right).
However, I'm not entirely sure on the interplay bootstrap / d3js, so I might have to use non-bootstrap means to fix the issues.
I look forward to working with you
