1. Instructions for Tasks 1-3 Use the same piece of paper Write down your names on the upper right hand corner. For each of the visualizations that you design, remember to write down the visual-data mapping!!

2. Task 1 – (15 minutes) Draw three visualizations of the dataset you are given. Try to avoid using a scatterplot please! TomJerry 3.55.0 3.14.8 2.75.1 4.30.5

3. Task 2 – (3 minutes) Think about the case if the first column is nominal (categorical) -- for example, the type of cheesecake that Jerry ate. Does each of your visualization still work? Answer this question for each visualization from Task 1. If not, design a new one. TypeNumber Regular5.0 Chocolate4.8 Banana5.1 Caramel0.5

4. Task 3 – (3 minutes) Think about the case if the first column is time -- for example, the dates that Jerry ate the cheesecake. Does each of your visualization still work? Answer this question for each visualization from Task 1. If not, design a new one. (3 minutes) TimeNumber 10:052.0 13:150.3 17:451.5 22:354.5

5. Instructions for Task 4: For part 4, be creative!! Given specific design constraints, you are encouraged to generate as many novel and weird visualizations as possible for 2-dimensional data (so called bivariate visualizations). The data used in your designs can be of any type (nominal, ordinal, quantitative; text, geospatial, trees, graphs, time, etc.). You need to note the data-visual mapping for each of your design. This is particularly true if your design is for a specific type of data (e.g. a hierarchy where the first variable is parentID and the second is childID). Again, you don’t have to program or use a ruler to make your visualization pretty. All you need to do is to express your ideas clearly.

6. Task 4a – (10 minutes) Axes are lines/Axis is line (15 mins) When axes are lines, we often call it Cartesian coordinate system. In the case that axes are lines, you’ve known some example such as scatterplot, bar chart and line chart. What else? Hints: Could you borrow something from part 1? And why? Could you change the shape/size/color/… of the visual elements? Could you change the position of the visual elements? Could you move the axis? Could you tweak the axis? Could you design a different mapping strategy even though the axes and the visual elements stay the same?

7. Task 4b – (10 minutes) Axes are not lines/axis is not line (15 mins) The pie chart is one of the examples where the axes are not lines. Visualizations like pie chart use the polar coordinate system. There are other designs that do not use a line (or lines) for its axis/axes, but also do not use the polar coordinate system. Hints: Try the polar coordinate system first, see how much you could borrow from 4a. In these coordinates systems, can you create new mappings that are different from part 4a? The polar coordinate system is where one of the axes is not line, what are other coordinates systems that one of the axes is not line? What about both axes? P.S. There are definitely tons of coordinates systems in geometry. If you know them, great. If you don’t, we don’t want you to spend time on understanding them here. E.g., Parabolic coordinates, Bipolar coordinates, Elliptic coordinates, Cylindrical coordinate system, Spherical coordinate system, Parabolic cylindrical coordinates…

8. Task 4c – (10 minutes) PART 3: No axis (15 mins) When there is no axis, how could you map the two columns to visual elements? Hints: shape, size, brightness, color, texture, angle, orientation, …
