 $Dom_svg:=SVG_New

 $Lon_line:=0

 For($Lon_ii;0;15;1)

    $Lon_column:=0

    For($Lon_i;1;16;1)

       $Txt_color:=SVG_Color_from_index(($Lon_ii*16)+$Lon_i)

       $Dom_rect:=SVG_New_rect($Dom_svg;$Lon_column;

       $Lon_line;11;11;0;0;"white";$Txt_color)

       $Lon_column:=$Lon_column+11

    End for

    $Lon_line:=$Lon_line+11

 End for
