"Part $1$

Few $(2009,$ Chapter $7,$ pages $143-188)$ provides numerous examples of static time series visualization: line charts, bar grap XB$02$ hs$,$ dot plots, radar graphs, and heat maps. Heer, Kong, and Agrawla $(2009)$ add horizon plots to the list. $[$See the syllabus for assigned course reserve readings for this week.$]$

Drawing on your experience in viewing time series visualizations, which of these graph types do you find most useful or easiest to understand? $($Provide a web link to a static time series visualization that you think is well constructed.$)$

How can the addition of an interactive component $($such as a linked time interval, time$-$interval slider, or time$-$ slider$)$ add to a time series visualization? $($Provide a web link to an interactive time series visualization that you think is well constructed.$)$

Part $2$

Describe special issues that may arise in working with data from the Internet of Things $($IoT$)$ or machine$-$to$-$machine $($M$2$M$)$ technologies.

How do you think data visualization might serve the needs of real$-$time analytics?"
