Answer 1

Question 1:

Interpolating distributions for missing data

Explanation:

Interpolation cannot be done by Data Visualization. It requires nemerical techniques.

Question 2:

Sunburst chart

Explanation:

Sunburst chart is used to visualize a hierarchical dataset through a series of concentric circles.

Question 3:

Line chart

Explanation:
Line chart connects a series of data points with a continuous line.

Question 4:

True

Explanation:

Pie chart is a circular praphic, which is divided into slices to illustrate numerical proportions.

Question 5:

The segments should be ordered lowest to highest

In Pie chart, we place The first segment : the largest slice, starting at 12 o’clock position and work our way around the circle.
