Visualisation of resource availability

Dear Forum,

 I want to build a layout where I have:

 for example two persons - person A and person B who are available on rotational basis(when Person A is in country, person B is out of country) and their availability to be shown on a timeline...and once one person's schedule is altered i can enter his new availability somwhere in MS project and it will be reflected visually on the layout. (something like as in inserted picture)

 And afterwards I'll be able to assign different activities against those persons.

 Coul you please advise how it is possible...

 Thanks
 Jim
