Looping svg rektangler fra databasen

Så vidt jeg kan se ud fra din kode, ser det ud til, at du bare skal kunne:

for i, row in enumerate(c): 
    box_x = ((row[3]-row[1])/2 + row[1] - 0.25)
    box_y = ((row[4]-row[2])/2 + row[2] - 0.25)
    move1 = box_y * 2
    try1 =  row[1] * 2  

    print('<rect id="rectangle{0}" class="rectangles" x="{1}" y="{2}" width="{3}" height="{4}" onmousemove="myFunction3()"><title>Owned by {5}</title></rect>'.format(i, row[1], row[2], row[3] - row[1], row[4] - row[2], row[6]))
