 Will generate a graph of the dependencies between cells in an Excel spreadsheet. Data extracted with `openpyxl` (<https://foss.heptapod.net/openpyxl/openpyxl>), the graph is generated with the `networkx` library (<https://networkx.org/>) and is visualized using `matplotlib`.
 
-This is a simple tool and maybe even naïve in its approach - it was hacked together in two evenings and would benefit from some refactoring and more features. It is meant as a starting point for further development.

-The way the graph is built is by iterating over all cells in the spreadsheet and extracting the references in the formula of each cell. The references are then added as edges in the graph.

-A cell within a range is considered a dependency of the range itself, but not of the other cells in the range.
