I didn't start from zero, but this children's dictionary of French in French was useful to me learning it: https://www.amazon.com/Mon-premier-dictionnaire-Roger-Pillet...

All the words it uses are defined within it -- of course with some circularity, but it's heavy on examples and pictures. It was intended for nonnative children taking classes in a style more like native immersion than is typical in schools. I wish more resources followed this philosophy.
