![]() ![]() Stacked Bar Graph: It is a bar style graph that has various components stacked together so that apart from the bar, the components can also be compared to each other.Bar Graph: It has rectangular bars in which the lengths are proportional to the values which are represented.The height of the rectangle is proportional to the values that are plotted. Column Chart: It is also called a vertical bar chart where each category is represented by a rectangle.You need to have information on the variability or dispersion of the data. For some distributions/datasets, you will find that you need more information than the measures of central tendency (median, mean, and mode). Although box plots may seem primitive in comparison to a histogram or density plot, they have the advantage of taking up less space, which is useful when comparing distributions between many groups or datasets. It can also tell you if your data is symmetrical, how tightly your data is grouped, and if and how your data is skewed.Ī box plot is a graph that gives you a good indication of how the values in the data are spread out. It can tell you about your outliers and what their values are. A boxplot is a standardized way of displaying the distribution of data based on a five-number summary (“minimum”, first quartile (Q1), median, third quartile (Q3), and “maximum”). Also play a role in combining categories as part of the data reduction process.Į nrol Now – Data Visualization Using Tableau course for free offered by Great Learning Academy.For variable derivation and selection means to determine which variable to include and discarded in the analysis.Supports the data cleaning process by finding incorrect and missing values.Primary use is the pre-processing portion of the data mining process.Powerful way to explore data with presentable results.The uses of Data Visualization as follows. If you’ve ever stared at a massive spreadsheet of data and couldn’t see a trend, you know how much more effective a visualization can be. If we can see something, we internalize it quickly. When we see a chart, we quickly see trends and outliers. Our culture is visual, including everything from art and advertisements to TV and movies.ĭata visualization is another form of visual art that grabs our interest and keeps our eyes on the message. We can quickly identify red from blue, and square from the circle. Our eyes are drawn to colours and patterns. In the world of Big Data, data visualization in Python tools and technologies are essential to analyze massive amounts of information and make data-driven decisions.Ĭontributed by: Dinesh Benefits of good data visualization By using visual elements like charts, graphs, and maps, data visualization tools provide an accessible way to see and understand trends, outliers, and patterns in data. This blog on data visualization techniques will help you understand detailed techniques and benefits.
