Patient/Caregiver Community Survey
(a) Patient usability	Error protection	Daily heat map (Figure 2A)	Using the visual above, what day would you think has the highest risk of a seizure happening?	January 27   February 3   February 5	0 = incorrect   1 = correct
	Error protection	Rose plot (Figure 2B)	Using the visual above, what time of day would you think has the highest risk of a seizure?	4 am   8 am   4 pm	0 = incorrect   1 = correct
	Error protection	Monthly heat map (Figure 2C)	Using the visual above, what month would you think has the highest risk of a seizure happening?	May 2019   October 2019   February 2020	0 = incorrect   1 = correct
	Error protection	Hourly line plot (Figure 2D)	Using the visual above, what time of day would you think has the highest risk of a seizure?	7 am   11 am   8 pm	0 = incorrect   1 = correct
	Error protection	Hourly radar chart (Figure 2E)	Using the visual above, what time of day would you think has the highest risk of a seizure happening?	1 pm   3 pm   5 pm	0 = incorrect   1 = correct
	Error protection	Daily line chart (Figure 2F)	Using the visual above, what day would you think has the highest risk of a seizure happening?	February 7   February 15   March 1	0 = incorrect   1 = correct
	Error protection	Risk gauge (Figure 2G)	Using the visual above and thinking about when the highest risk of a seizure is occurring, please select the most appropriate answer.	I’m currently at the highest risk level of today   My risk level may increase throughout the day   My risk level is the lowest it will be today	0 = incorrect   1 = correct
(b) Patient functional suitability—reducing unpredictability	Functional appropriateness (for reducing unpredictability)	When thinking about the risk level of a seizure happening, does it seem like this visual would help relieve anxiety and provide a better way to prepare for seizures?		Seems helpful but does not apply to me   Seems very helpful   I do not understand this visual   Other (please specify)	0 = I do not understand this visual or other   1 = Seems very helpful, or seems helpful but does not apply to me
(c) Patient functional suitability—evaluating seizure patterns	Functional appropriateness (for evaluating seizure patterns)	Please rate the usefulness of this visual in the context of your seizure risk and predictability.		5-item Likert rating	Likert 1 (not useful)   Likert 2   Likert 3   Likert 4   Likert 5 (very useful)

Clinician Community Survey
(d) Clinician usability	Appropriateness recognizability	I would use this visualization frequently in clinical care.		5-item Likert ranking	Likert 1 (strongly disagree)   Likert 2   Likert 3   Likert 4   Likert 5 (strongly agree)
	Operability	The visualization was easily understood.
	Learnability	I found understanding this visualization to have a steep learning curve.
(e) Clinician functional suitability	Functional appropriateness (for interpreting seizure diary patterns)	This visualization will help interpret seizure diary patterns.
	Functional appropriateness (for evaluating need for medication changes)	This visualization will help assess patients to identify needed therapy changes.
	Functional appropriateness (for guiding counseling on safety)	This visualization will help counsel patients on seizure safety until next clinic visit.
(f) Clinician performance efficiency	Time behavior (ease of integration into clinical workflow)	This visualization would integrate well into my clinical workflow in patient management.
