Scatter plot chart vs code flower (force directed) chart for data visualization

We've got a scatter plot chart which represents some data.

Now, the client wants us to replace it with this code flower (force directed) chart.

Implementation efforts is not the problem for us, however I believe that it will degrade the UX.

For scatter plot chart

  • All the data is available in one shot

For code flower:

  • The user needs to hover on each point to get the sense of the data
  • The user needs to click on each point to get the drill down data

I'm not at all a UX guru, however my conscience says, the client will degrade the product customer's UX.

Please help me decide:

  • Shall I stop them from doing this?
  • Is it really an improvement or just a fancy feature?
