Scattering vertices in the page

Is there any option to better distribute the vertices in the page? As you can see in the picture below, there are a lot of space in the page, but it seems that vertices are close to each other when I zoom in. The command I am using is:

dot -Ksfdp -x -Goverlap=scale -T pdf -o my.pdf my.txt

How many nodes & edges?
Can you share the dot source?
Have you tried other layout engines? If so what was the result?
Until we know what the input is about, it is difficult to tell you what to change.
Have you looked at the sfdp-related attributes on

Less than 10 vertices and about 7K edges.
