So many posts in the last few days, apologies. I have a really important interview coming up where I have to use a dataset and present it through Tableau. I have made various graphs etc to visualise the story and I want your honest, and as harsh as possible, opinion! I would much rather it is completely slated and I don't embarrass myself presenting it than be incorrectly told it is fine... I think because I have been consistently on Tableau for hours trying to create this that I've gone Tableau-blind and can't work out what looks best anymore
I plan to properly place everything together once I've decided what to use so don't worry too much about organisation of each graph or little mistakes such as axis or titles etc as I will sort that all out when I piece it together. I just want to know which graphs are junk and which effectively illustrate the data
The data I am working with (attached) is basically poll results for Americans preference of rep/dem congressional results for the upcoming election. No geographical data included, I'm just working with the answers to the question "who wold you vote for in the congressional election if it were today". So % that chose democrat, % that chose republican - as well as the date of the poll and whether the respondent was a registered voter or considered a 'likely' voter. I will attach the workbook but there are a few and they are very disorganised right now so I think screenshots are a better way to view them.
^ Viewing % that chose each party over time
^ The ratio of democrat/republican preference over time
^ A simple look at the overall average of preferred party. I like this one anyway as almost a header-type feature to the dash I will make as it is simple and straight away shows the user the overall preference?
^ Looking at each party's increases and decreases in preference over time
^ Simple graph showing the % that answered Dem or Rep over time.
^ An alternative to showing the difference in party preference overtime but on the same graph.
Please be harsh
(PS, I am going to add a page to discuss how the findings for likely voters was different to that of registered etc but for this post I mostly just want opinions on displaying these graphs I screenshotted)
