Bar charts are good for comparisons, while line charts work better for trends. Scatter plot charts are good for relationships and distributions, but pie charts should be used only for simple compositions — never for comparisons or distributions.Ask yourself how many variables you want to show, how many data points you want to display, and how you want to scale your axis. Line, bar, and column charts represent change over time. Pyramids and pie charts display parts of a whole. While scatter plots and treemaps are helpful if you have a lot of data to visualize.Line Graph
A line graph reveals trends or progress over time, and you can use it to show many different categories of data. You should use it when you chart a continuous data set.
What is the most commonly used graph to show : Bar Graphs
The universally-recognized graph features a series of bars of varying lengths. One axis of a bar graph features the categories being compared, while the other axis represents the value of each. The length of each bar is proportionate to the numerical value or percentage that it represents.
Which graph is easier to read
Bar Chart. Bar charts are frequently used and we're taught how to read them starting at a young age. The most simple bar charts, those that illustrate one string and one numeric variable are easy for us to visually read because they use alignment and length. Additionally, bar charts are good for showing exact values.
Why use a bar graph : A bar chart is used when you want to show a distribution of data points or perform a comparison of metric values across different subgroups of your data. From a bar chart, we can see which groups are highest or most common, and how other groups compare against the others.
Bar charts are effective at comparing categories within a single measure and one of the most common data visualizations. clustered bar chart
To graph three variables, the best choice is clustered bar chart. We can graph three variables using many programs such as Excel, power point etc. A line graph is a graphical representation of data that changes over a period of time. It consists of a horizontal x-axis and a vertical y-axis.
How to know what type of graph to use
If you want to show the relationship between values in your dataset, use a scatter plot, bubble chart, or line charts. If you want to compare values, use a pie chart — for relative comparison — or bar charts — for precise comparison. If you want to compare volumes, use an area chart or a bubble chart.When you should use a histogram. Histograms are good for showing general distributional features of dataset variables. You can see roughly where the peaks of the distribution are, whether the distribution is skewed or symmetric, and if there are any outliers.Bar graphs probably the most versatile way of displaying population data. They are often used to show population growth over time but they can also show things such as the relative proportions of different groups in the society or they may be used to compare populations of different places. How to Choose the Right Visualizations
Tabular format is best used when exact quantities of numbers must be known.
Line charts are best used when trying to visualize continuous data over time.
Bar charts are best used when showing comparisons between categories.
Pie charts are best used to compare parts to the whole.
Why is bar graph easier : A bar diagram makes it easy to compare sets of data between different groups at a glance. The graph represents categories on one axis and a discrete value in the other. The goal is to show the relationship between the two axes. Bar charts can also show big changes in data over time.
When to avoid bar chart : When to avoid bar charts:
Summarizing continuous data. Bar charts can obscure the nature of the underlying data when it comes to summarizing continuous distributions.
Long time series.
Correlation.
Geospatial information.
When to not use bar graph
In contrast, bar graphs should not be used to present summary statistics (e.g. mean and standard error or standard deviation) for continuous data [1,2]. Datasets with many different distributions may have the same summary statistics. The actual data may suggest different conclusions from the summary statistics alone. Here are some of the most important data visualization rules according to the data experts that we surveyed.
Keep it simple.
Add white space.
Use purposeful design principles.
Focus on these three elements.
Make it easy to compare data.
Blend your data sources.

How to visualize data with 3 variables : A level plot colors a grid spanned by two variables by the color of a third variable. The term heat map is also used, in particular with a specific color scheme. But heat map often means a more complex visualization with an image plot at its core. Superimposing contours on a level plot is often helpful.
