Answer:
A bar chart or bar graph is a chart or graph that presents categorical data with rectangular bars with heights or lengths proportional to the values that they represent. The bars can be plotted vertically or horizontally.
For example, if you had two houses and needed budgets for each, you could plot them on the same x-axis with a grouped bar chart, using different colors to represent each house. See types of bar graphs below.
two dimensional diagrams, the areas of the diagrams are used to represent the magnitudes. Rectangles, squares and circles with area proportional to the observations are used to represent each category of these, circles are most commonly used. Such diagrams are called pie – diagrams.Different types of graphs
Line graph. Line graphs illustrate how related data changes over a specific period of time. ...
Bar graph. Bar graphs offer a simple way to compare numeric values of any kind, including inventories, group sizes and financial predictions. ...

Scatter plot.Bar Graph. Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.A graph drawn using rectangular bars to show how large each value is. The bars can be horizontal or vertical. See: Histogram. Bar Graphs.bar graph is a chart that plots data using rectangular bars or columns (called bins) that represent the total amount of observations in the data for that category. ... Bar graphs are commonly used in financial analysis for displaying data.simple bar chart consists of a grid and some vertical or horizontal columns (bars). ... There are several different types of charts and graphs. The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs.Bar graphs are the pictorial representation of data (generally grouped), in the form of vertical or horizontal rectangular bars, where the length of bars are proportional to the measure of data. They are also known as bar charts. Bar graphs are one of the means of data handling in statistics.
