Week 13: LGBT Rights across the world - sah403 - 11-19-2014 11:32 AM

This is a visualization about Lesbian, Gay, Bisexual & Transgender Rights across the world.

Following is the link to the original Visualization
http://www.theguardian.com/world/ng-interactive/2014/may/-sp-gay-rights-world-lesbian-bisexual-transgender#country:646,862

The rights are categorized into five categories where each category is assigned a color. The countries are spread spatially in the form of a semi-circle and are divided into five categories based on the continent to which they belong. The plot area is divided into five concentric rings where each ring is used to represent about one of the categories of rights. The area allotted for each country in a ring is filled with associated category color, if that country has rights for LGBT in the law. Grey color is used if LGBT is illegal or law is unclear.

The visualization uses area as mark; color and space as identity channels. Color encoding is used to indicate the number of rights in each category that are in the law. Less saturated colors indicate that there are only some rights and more saturated color indicates that it is completely legal.

The visualization also has two tabs: Country and Population. The default view is the visualization associated with the first tab: Country. The visualization of second tab: Population is similar to that of the first, except that additional area encoding is used to represent the population of the country.

The visualization has interactivity built in. On hovering the mouse over the plot, the corresponding country name is displayed and the country is highlighted in the map. Although the following interaction is not particularly related to the visualization, one may also select continent from the list below the visualization and the desired country. This displays the details about the country in the form of text below the list.

I feel that the visualization is very effective in conveying the information that it has to convey. I liked the hues used in the visualization. To a normal eye, I believe that this visualization with respect to colors would have a very aesthetic appeal. But both the colors: red and green have been used which would difficult to distinguish by a person suffering from protanopia or deuteranopia. Similarly both the colors: yellow and blue have been used which would be difficult to distinguish by a person suffering from tritanopia. I also feel that the second visualization is redundant. There is no practical use in size encoding of total population of the country. Instead of the total population of the country, if the population share of LGBT had been used, then the visualization would have made more sense. For example it would indicate how even if many LGBT lived in a country there are no prescribed laws for them. Another feature that would improve the visualization is the ability to select the country by directly clicking on the map. Looking up data for a particular country will be easier this way than searching through the sectors.

Overall, this is a good visualization with minor flaws.

I like this visualization and it is interesting. I agree with Sah403 for the most part. This visualization conveys clear information and has interactivity. I can identify which region offers more rights to LGBT people and which doesn't. I also like the color hue encoding that looks harmonious and comfortable. It offers additional visualization for detailed country or region that is good for user who wants to learn more. I would like to improve this visualization just like Sah403 mentioned, select a region/country on the map and it would be highlighted on the visualization. I think that would be easier for user to look up data for a specific area. In general, this visualization is good.

This is a quite interesting visualization and I think it is very efficient to provide the viewers with information. I agree with the critiquer that the hues used in this vis are appropriately chosen and have a very aesthetic appeal. And I also felt that some pair of colors are not too easy to distinguish the information they represented. The critiquers thought that the second visualization is redundant and have no practical use, for which I hold a different opinion. I think the second vis provides totally different information and the size encoding of total population of the country is useful.

I agree with u0875378 that the size encoding of population of each country is useful because that is linked to the size of LGBT group. Without the statistics of the population of LGBT in all of those countries, using the total population is reasonable.

I also agree that the use of map in this visualization can be improved. The current usage is just visualize the selected country in the world map. It does not tell anything further than that. Looking for a specific country is hard in this presentation. Enlarging the map and make it interactive would be nice. For example hovering over the country will highlight the LGBT status of the country instead of hovering over the semi-circle can be a useful improvement.

I liked the visualization. Specifically I liked the usage of area encoding to represent the population. As most people have already suggested I too agree that the visualization could have been improved by having a reverse mapping. Where on hovering a country in the map its information is displayed. The best and worst places at the bottom could also have been shown using a map with color encoding to represent how safe the country is.

I liked this visualization quite a lot mainly due to its effective interactivity. The different hues for "legal" and "some rights" was appropriate. However, I cannot vouch for the color blind.
I also feel that more information could be provided along with the name of the place during mouse rollover.
I feel like these small adjustments could bring drastic changes to the graph in a good way.

The pie chart is beautifully design with different hue for different rights. Interactivity in this visualization is good but not good enough.

- The only interactivity exists in the pie chart, but if I want to click on the map to reversely get respective information, it doesn't show anything. Clicking on the pie chart doesn't result to a respective changing in the below panel (which is for detailed information)

- Another issue is if I click on China for twice, it shows two China in the selected countries panel. This should be a bug...

I think Sah403 wrote a very good critique. The use of a semi-circle (rainbow) results in less area for the wedges that are closer to the center. I find it strange that Protection Against Hate Crime was placed in the inner-most ring, where the area is smallest, because I would think this is one of the most important rights. Perhaps the creator was trying to emphasize how few countries provide that right by making the positive contributions seem smaller?
I don't understand how the countries are sorted within each continent. It is not alphabetically or by population and does not seem to be based on how many rights are given. It would be nice if the countries had some kind of intuitive sorting.

The countries within a continent are sorted based on their geographic position

I have never seen a map for detail and radial visualization for overview till now. This is a good visualization but they had a bad choice of having a overview and it should have been in my opinion been on the map. Although this was discussed by some of the students. I just wanted to bring the overview+detail into picture.
I liked the critique too. I totally agree that size encoding popoulation wise was less useful for me to visualize any other data other than China's.
