Keep graph aspect ratio while zooming?

We are using plotly to draw the geometry of an electrical device. When the user zooms in, I would like to keep the aspect ratio of the x-axis and y-axis constant so the geometry does not look distorted. Is this feature available in plotly or plotly 2.0? Thanks!

We’re planning on adding this feature in the next few months.
