I particularly liked this representation of the data because it is interesting that these abstract lines represent countries but it is quickly identifiable. You get to explore each line that looks the same until you hover over and the data for the country appears. The different colors on each end of the vertical lines represent the two genders included for each country and easily shows the large gap. I like the play button that changes the data over several years to show how to numbers change.
The text is easy to read at the top and the key clearly labeled.I'm not sure how the countries are placed though. I do also like how there is an "About the data" button to learn even more without cluttering the diagram.
It is clear the author of this work is in support of women's rights, and showing the "glass ceiling" that is placed over women and limits their upward mobility.

This second example took me a little bit longer to understand how things were organized and the meaning of the data but not by much. My favorite part is the list of countries with their flags below the year to show what year women gained the right to vote in each country. The top part of the data (the chart) doesn't really do much for me. I don't find it extremely useful or easy to read other than it opening up the list of countries and toggling between years below. This could be designed better I believe.
The general knowledge of this information makes it totally believable, even without seeing the source but that is probably bad practice. The typography is similar to the previous one, not super intriguing but easy to read.
