Graphs are important in the visual illustration of data relationships. The main purpose of using graphs is for presentation of data to make it easily comprehensible and interpretable. Data-sets that do not show any significant trends or patterns cannot be represented in a graph. It should however be noted that different types of graphs have varying uses, depending on the type of data being represented.
When a bar graph most suitable in professional and everyday life
A bar graph is made up of columns (bars) that are either horizontal or vertical. Bar graphs are normally suitable in drawing comparison of one variable between several groups, and tracks changes over time. For instance, the average blood sugar content of a cohort of diabetics and a control group can be clearly represented in a bar graph. Through bar graphs, everybody, irrespective of their educational backgrounds can easily identify and interpret the illustrated data.

When a pie chart is most suitable in professional and everyday life
A pie char is a special graph that represents data using pie slices such that every portion is an illustration of the relative data sizes. Every segment in the chart represents a different group. Pie charts are used when comparing parts of a whole. For example, the composition of various gases in the air.
Graphical Illustration
When representing data on the changes in minimum wage of a nation, line graphs are most suitable. The reason for this choice is because line graphs are efficient when tracking changes in a variable over short term periods ( Kunz, Ley, & Steenson, 2019) . Line graphs can capture even slight fluctuations, hence most suitable.
