Charts were based off of Scott Murray's examples. Legend was based off of this example and tooltip was based off of this example.

###Housing Demographics for Non-White and Non-Black Persons 2014

• This chart shows the breakdown of the housing population for the three smallest minority groups: American Indian and Alaska Native, Asian, and Native Hawaiian and Other Pacific Islander.
• Line marks were used
• Magnitude Channel encoded using position on an aligned scale (or length)
  • Discriminability is maintained because the viewer can easily compared the rightmost point of bars
• Identity Channel encoded using color hue
  • Discriminability is maintained because we have a small number of categories, so the viewer is not overwhelmed by a large number of colors.

###Men and Women Participants in Summer Olympics Each Year

• This chart shows the number of men and women participating each year during the Summer Olympics. The number of participating countries is mapped to the area of the circle. You can hover over a data point to see the year and the number of participating countries.
• Point marks were used
• Magnitude Channel encoded using area
• Discriminability is maintained by defining a scale of acceptable radii which can be mapped to. That way we are guaranteed that our circles do not become too large and obscure other data points.
• Identity Channel encoded using spatial position, so years that there was a large number of men and women are at the top right, or years where there were few women are towards the bottom side.
• Discriminability is maintained because the viewer can easily see groups of points since spatial region is the most effective categorical encoding.
