Keys to good visual design

Before adding something to a dashboard:

• Does this contribute to the story?
• Is this the right visual element?
• Is this visual element necessary?

Promoting the story

• What story am I trying to tell?
• Does this new visual align with the story?
• Will my audience see it that way?

Story-telling in a world of choices

• Filters and slicers give users flexibility
• Flexibility limits your control
• Understand user needs and the types of stories they can pull from the data
