This allows audiences to recognize patterns more quickly. 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. The interconnected objects are represented by points termed as vertices, and the links that connect the vertices are called edges. Graphs are represented to a scale, but diagrams are required to be constructed to a scale. In this article, the techniques of data and information presentation in textual, tabular, and graphical forms are introduced. The test of a good graph depends on the case with which the observer can interpret it. Adjacency List There are other representations also like, Incidence Matrix and Incidence List. Ø The data become more logical (clear).. Ø The comparison becomes easy.. Ø Can derive the conclusion from data very quickly.. Ø Give the spread of the data.. Ø Reduce space for data representation.. Ø Helpful in statistical analysis.. Thus economy in cost and energy should be exercised in drawing the graph. Types of Graphical representation which will cover here are and why: Scatter Plot: With the help of the graph, we can see in which direction our linear regression model is going, whether there is any strong evidence to prove our model or not.

Furthermore, any hidden trend present in the given data can be noticed only in this mode of representation. Tables are commonly used, and there are many graphical and numerical methods as well. • Graphs are useful in representing data with distinct units, such as years and months. As with many simple yet effective ideas, Euler’s approach stood the test of time and yielded graph theory, a branch of mathematics that explores graph properties to this day. It is used in many academic and professional disciplines but most widely so in the fields of mathematics, medicine and the sciences. (B) DFS and BSF can be done in O(V + E) time for adjacency list representation. By, Sana Rehman, Assistant Professor, SCMS, Pune 2. Today, we’re sharing a list of the various types of data organization and how you … Graphical Representation of Data PPT (Line Diagram, Bar Diagram, Histogram, Frequency Curve, Ogive and Pie Chart) What is graphical representation?

Textual presentation of data means presenting data in the form of words, sentences and paragraphs. Ease of analysis: Data tables are frequently used for statistical analysis like calculation of central tendency, dispersion etc. Data visualization is the process of turning your data into graphical representations that communicate logical relationships and lead to more informed decision-making. If you need to present all of the details of each record, then tables are the way to go. 1. An attractive representation of data is graphical representation. A Pareto graph or chart is a type of bar graph that also features a line graph.

These operations take O(V^2) time in adjacency matrix representation. Following are the main drawbacks/ limitations of graphs. However, if your reader is unfamiliar with the data or the data is complex, comprehension will suffer. We use these representations in order to gain bet-ter insight and understanding of the problem we are studying - pictures can convey an overall message much better than a list of numbers. Typically, bar charts are created with qualitative data (nominal or ordinal variables) while histograms are created with quantitative data (interval-ratio variables). Frequency Polygons A frequency polygon is a graph showing the differences in frequencies or percentages among categories of an interval-ratio variable. The Advantages of Tabular Presentation. They can also be edited and shared. There are 2 big differences between adjacency list and matrix. Ease of representation done in O ( V + E ) time in matrix.
