Write a function called $`$data$\_$to$\_$dictionary$`$ that converts the data into a dictionary such that:

$1.$ There is a single key for each character in Hamilton.

$2.$ The value corresponding to each key is a list of the characters to which that key links. The list should contain repeats if there are multiple links.

Here's an example of the desired behavior on a fake data set.

$```$python

data $=[("$a$","$b$"),$

$("$a$","$b$"),$

$("$a$","$c$"),$

$("$b$","$c$"),$

$("$b$","$a$")]$

$$

data$\_$to$\_$dictionary$($data$)$

# output

$\{"$a$"$ : $["$b$","$b$","$c$"],"$b$"$ : $["$a$","$c$"]\}$

$```$
