i have data of 3D point from a N-Body simulation the data of the 3D point are in a csv file i am able to plot the point from this file the problem is that the data are from 5000 body but my csv file have 2.5million row so i would like to animate to see point 5000 by 5000 for exemple row 0 to 5000 represent the initial position of the 5000 body row 5000 to 10000 represent the position of each body after a time interval dt and so on so basicaly i would like to see the movement of these body by ploting row 0-5000 then ploting row 5000-10000 then 10000-15000 …
