It is unlikely that your data are currently at this format. You probably need to reformat your data first using another tool like R. The following document gives a few example on how to reformat the most common types of input to get a json file.

• Centering (attracts every node to a specific position)
• Collision (consider nodes as circles with radius and try to avoid overlapping)
• Links (pushes linked nodes together, according to a link distance)
• Many-Body (apply general attraction (if positive) or repulsion (if negative) between nodes)
• Positioning (push each node towards a desired position).
