I see. This graph is pretty confusing imo. My first idea for a visualization is to use a stacked bar chart that always adds up to 100% with "No it's not a vehicle" above "Yes it is a vehicle." Use 4 colors, dark red, light red, dark green, light green, and emphasize your choices with the dark ones.

Add a couple checkboxes with interactivity:

- Show only "Is vehicle" bars

- Show only "Is not vehicle" bars

- Show only answers that agreed with me

- Show only answers that disagreed with me

And a "toggle colorblind mode" although I'm not sure what colors would be ideal for that.

Any other ideas for how to make this thing actually readable?
