Some prompts are less obvious and open to interpretation than others. Any interpretations are welcomed as long as they fit the overall category (comparisons). So, for "Neo", it could be a theme, a form, or something else. Neo = new or Neo = Matrix, etc.

Thanks for asking! You may interpret it in your way. Any interpretations are welcomed as long as they fit the overall category (comparisons). It could be a theme, a form or something else. For instance, it could mean new or recent to compare the new to the past.

The galleries are generated based on the hashtags. In case your
#dataviz
is featured on a wrong day it is likely because you got it wrong... 😬 If it doesn't show up, it means you did not include
#30DayChartChallenge
or a hashtag of the day (e.g.
#Day1
).

Thanks :) Wow, that's a lot of categories! Do you know that the optimal number of categories for pie and donut charts is somewhere between 2 and 5? The same applies to color, more than 6-8 distinct colors are hard to distinguish.
