I am looking for a simple web-based 2D landscape design tool for our customers. Round icons representing plants are draggable from a side column and placed in a grid on the screen. I would like to also include a parameter in my Wordpress Post Admin that allows for plant radius sizing for individual plants. Users will pick plant by name and the icon will size itself to the grid scale. Ther should also be some basic ability to draw lines and rectangles for lawn structures. The plants dragged into the grid will be listed in another side column and is sendable for a customer quote, possibly using "Quote Cart" plugin for Wordpress framework. An example of what I am looking for is Garden Planner Online at smallblueprinter dot com.
