        graph.DrawRectangle(top_left=(i * BAR_SPACING + EDGE_OFFSET, graph_value),
                            bottom_right=(i * BAR_SPACING + EDGE_OFFSET + BAR_WIDTH, 0), fill_color='blue')

The coordinate system is (0,0) is the bottom left corner. (500,500) is the top right. This is identical to the positive portion of a 4-quadrant graph. You can just as easy define a traditional graph with 0,0 being in the center of the diagram. For that you use (-250,-250) for bottom left and (250,250) for top right.

Here's the image produced when using a 500x500 size.

This 100x100 size was generated by changing only the line of code defining the pixel size of the graph (GRAPH_SIZE)

Thanks. I'm definitely replacing MPL with this. It's fast flexible, customizable and doesn't require an additional 50MB for a simple bar graph :)

Working on some things. Going to push the SQl data into it, and customize some more.
