    22This project is focused on using STL containers in order to graph data on a one-dimensional and two-dimensional (and if time allows, 3D!) plot. The plot would be written in an `svg` image, compliant with the W3C standard. The goals of the project are as follows:
    33
    4  * To provide an easy syntax for graphing data
    54 * To let users produce a simple plot with minimal intervention by using sane defaults
    65 * To demonstrate how to incorporate SVG images into Boost documentation

    146  * Changing or setting the x_scale after calling my_graph<<draw_axis() makes the axis not be drawn.
     130 * Changing or setting the x_scale after calling my_graph.draw_axis() makes the axis not be drawn.
    147131   * This is caused because I store points after setting the graph. I will fix this by storing infinity as +NaN in the point, and when outputting, writing it at a location far off the graph
