http://e2d3.org By using E2D3 (Excel to D3), you can create a dynamic and interactive graph via Excel without programming, because E2D3 bridges a gap between a statistical tool Excel and a graphical tool D3.js. E2D3 also provides a middle-ware by which D3 programmers easily connect a D3 codes and Excel sheets and a platform in which the D3 programmers simply submit their own D3 graphs to the world.
