Statistics Interview Question: How do pictographs differ from bar graphs:

Knowledge of statistics is crucial in the field of data science. Data visualisation is also important when working with data science because it is important to present data derived from statistical work in a logical and orderly fashion that will enable people to understand it. Two such visualisations that are similar but contain differences are bar charts and pictographs.
