Hi @Ankit_Malhotra,
welcome to Coda Community! 
Currently there is no such feature (yet), but - if you are willing to spend some time with SVG - have a look at @Paul_Danyliuk post:
MEGA TRICK: SVG in Coda (one step away from generated charts and mind maps!).
Perhaps not the best plug-n-play solution, but really flexible to build your own implementation 
Enjoy!
