This module renders text graphs to visualize data on the terminal. A typical text graph looks like a bar graph as shown below:

 label1     3786 |----+----1----+----2---- ... ----+----7----+----8----+----9----+----|
 label2     3653 |----+----1----+----2---- ... ----+----7----+----8----+----9----+-
 label3     1055 |----+----1----+----2----+--
 label4      308 |----+---
 label5       70 |-
 label6      404 |----+----1
 label7       71 |-
 label8       32 |
(each '-' is approximately 37.860 units.)
val render : ?narrow:bool -> (string * float) list -> string

Renders a text graph given labels and values. The list should be non-empty and the specified values must be positive numbers. Setting narrow enables narrower graphs.
