Program/Site to Make Garden Map?

We have considerable flower gardens in our yard and would like to create a map this summer showing where everything is planted so we can study it next winter when deciding what to buy for spring. Does anyone know of a program or online site where you can create a diagram like this? Thanks!

I belong to the Lowe's garden club and used their garden designer and planner last year to diagram my beds, pathways and secret garden. It is free to be a member,they send you project starter gift cards and a monthly magazine filled with great ideas and specials for members. (The mulch calculator is awesome, too).
