Run bower update Create a choice activity. Log in as student(s) and vote on the choice activity. If the choice results are not published, no results should be visible under the alternative answers. If the choice results are published, the results should be visible under the alternative answers, in a new "card". The graph should be displayed first, it should be possible to click (tap) the pie slices and receive information about it. Under the pie chart, the different alternative answers should be listed. Under each of these, the amount of user in percentage that chose the alternative should appear (all the percentages should add up to 100%). In addition, for each alternative the users (profile picture + name) that chose the alternative, should be listed on the left in a vertical list (if this is turned on).
