Suggestion in regards to "Formatting for lines" for ASCII2SVG

README.md

Introduction

In the documentation for ASCIIToSVG, in regards to formatting (shape, color, style, etc.) it's author wrote:

If you have thoughts on how to do this for lines, please do let me know.

Well... I may have a suggestion.

Format for boxes

The format that is used for boxes is like this:

.-------------.  .--------------.
|[Red Box]    |  |[Blue Box]    |
'-------------'  '--------------'

[Red Box]: {"fill":"#aa4444"}
[Blue Box]: {"fill":"#ccccff"}

Format for lines

I would think using the same format that is currently used for boxes could also be used for lines:

-------------[Red Line]-------------->

<------------[Red Line]---------------

[Red Line]: {"fill":"#aa4444"}
[Blue Line]: {"fill":"#ccccff"}

What about vertical lines you say? Same principle applies:

    ^               |
    |               |
    |               |
    |               |
[Red Line]      [Blue Line]
    |               |
    |               |
    |               |
    |               V

[Red Line]: {"fill":"#aa4444"}
[Blue Line]: {"fill":"#ccccff"}

Disclamer

As I am not at all aware of the inner workings of the code this may be too simple a suggestion with all sorts of downsides. Working from the perspective of Idealized Design, however, this would be my suggestion.

So... Comments?
