#### 1. What data are being visualized? Where did they come from? ##This graphic came from a paper titled “An Anthropocene map of genetic diversity”. ##This map shows the global distribution of knowledge and ignorance. How much do we know about the diversity of mammals and amphibians together (A), mammals (B), or amphibians (C). The x axis indicates the taxomic coverage by percentage on the log scale and y axis indicates sequence availability (DNA), so low taxonomic coverage and low availability of sequences are the violet color cells. Green cells indicate higher taxonimc coverage with higher availability of DNA. Red and light blue indicate the in between.
#### 2. Which data dimensions (observations/rows, variables/columns) are mapped to which visual cues? ##Sequence availability (Y values) and taxonomic coverage (X values) are variables used in this distribution map. As I mentioned in the first question, the colors correspond to varying sequence ability and taxonomic coverage for each observation grouped by regions.

3. How does this shape your understanding of the data?

This shape indicates a geographic spread of weatlth of data and genetic diversity when considering biodieversty of mammals and amphibians.

4. If you liked the visualization, what is it doing well?

It sheds light on the unequal distribution of knowledge when we consider the genetic biodiversity of mammals and amphibians on a global scale. If we are making important conservation decisions it is important to have a fair and consistent scale to be able to compare areas of high biodiversity in order to save time and money for conservation. For example, South America shows a lot of violet squares in an area where we know there is high diversity (tropical rainforests), so allocating more funds and time to conservation of those areas would help make informed decisions on conservation of areas in that region. In terms of form, the color shcheme works well for this map in terms of differentiating cell colors from each other.

5. If you disliked the visualization, what would you change?

Red and green are flagged as difficult to distinguish for color blindness. I would change the color scheme in that sense. I really like the overlay of the map, but I wish that the way they did their sampling was different so that there were more abundance of cells and that they were smaller.
