Sand drawings form a part of many cultural artistic traditions.
Depending on the part of the world in which they occur,
such drawings have different names such as
*sona*,*kolam*, and*Malekula*drawings.*Gaussian graphs*are mathematical objects studied in the disciplines of graph theory and topology. We uncover a bridge between sand drawings and Gaussian graphs, leading to a variety of new mathematical problems related to sand drawings. In particular, we analyze sand drawings from combinatorial, graph-theoretical, and geometric points of view. Many new mathematical open problems are illuminated and listed. **Length**:- The paper is 10 pages.
