Problem-1

Read the attached IEEE paper on What Makes a Visualization Memorable? The paper tested seven hypotheses about what makes a visualization memorable. Discuss each of the hypotheses. In particular, is the collected data confirm the hypothesis?  Justify your answer with supporting arguments including statistics and appropriate visualizations from the paper. 

H.1 Participants will perform worse (i.e., overall have a harder time remembering visualizations) as compared to natural images/photos.

H.2 A visualization is more memorable if it includes a pictogram or cartoon of a recognizable image.

H.3 A visualization is more memorable if there is more color.

H.4 A visualization is more memorable if it has low visual density.

H.5 A visualization is more memorable if it is more “minimalist” (i.e., “good” data-ink ratio).

H.6 A visualization is more memorable if it includes a “familiar” visualization type (i.e., basic graph type taught in school).

H.7 A visualization is less memorable if it comes from a scientific publication venue.

Problem-2

This homework is built upon the last homework (homework-2). 

1. Problem-2.1: The replacement rate is 2.1 children per woman. According to one report: “If the replacement rate in a country is significantly below 2.1, the population will shrink over time. If it’s much higher than 2.1, the country will have much younger population down the road, which can cause problems. Younger populations, for example, show greater rates of violence and crime.” You are asked to highlight the data points of each country that are outside the range. For this exercise, let’s set the upper limit to 3.0 children per woman (replacement rate + 0.9) and the lower limit as the 1.2 children per woman (replacement rate – 0.9).

Develop a visualization to allow the user to select a country (one country at a time) of his/her choice. The visualization should show the time-series of the country’s fertility rate and highlight the data points that are outside the limits that we defined.
