Scatter Plot
This type of graph is used to determine the relationship between two features. It is also called as scatter chart or scatter graph. As the name indicates, points are scattered over the graph for the two variables.
Algorithms:
It is effectively used for data analysis in Linear Regression models.

Line Graph
This graph is considered to be one of the basic starting point for data visualization. This is mostly used in time series data visualizations. It effectively shows progress over a period of time.
Algorithms:
It is also helpful to determine the efficiency of the Linear Regression model.

Histogram
This graph is commonly used to display corporate data. It is easy to understand and widely used in Machine Learning.
It is used to show the underlying frequency distribution of the continuous data which allows the inspection of the data for its distribution (e.g., normal distribution, Binomial distribution, Bernoulli Distribution), outliers, skewness, etc.
Algorithms:
It is also helpful while doing Exploratory Data Analysis.

Pie Charts
In this graph a circle is divided into sectors or slices that each represent a proportion of the whole.
The arc length of each slice (and consequently its central angle and area), is proportional to the proportion it represents.
The graph/chart is useful for displaying data that is classified into nominal or ordinal categories.
Algorithms:
It is also helpful while doing Exploratory Data Analysis. Also used to represent data after use of classification algorithm like Logistic Regression and Clustering algorithm like K Means.
