Welcome to your interview.
The question is on your right: Data Visualization with Highcharts. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Have you worked with Highcharts or similar data visualization libraries? If so, what challenges did you face?
