The horizontal label across the bottom and the vertical label along the side tells us what kinds of data is being shown. The horizontal scale across the bottom and the vertical scale along the side tell us how much or how many. The points or dots on the graph represents the x,y coordinates or ordered pairs.

## What relationship does the line graph describe?

The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear.

## What is the difference between line graph and broken line graph?

A variation of a line graph is a broken-line graph. A line is used to join the values, but the line has no defined slope. However, the points are meaningful, and they all represent an important part of the graph. Usually a broken-line graph is given to you, and you must interpret the given information from the graph.

## What are the limitations of a bar graph?

Disadvantages: Bar charts that attempt to represent wide ranges of numbers will struggle to efficiently communicate their message. For example, a bar chart for the numbers 5, 6, 10 and 378 will lend extreme visual weight to the highest value and make the relative values of the other measurements appear irrelevant.

## What are the advantages and disadvantages and purpose of using charts and graphs?

The advantage to using graphs and charts is that they can display a lot of information is an easy to understand format. For example, a line graph is a great way to show trends over a period of time. You could put numbers in a table, but a line that is consistently going up is much more accessible at a quick glance.

## What is the purpose of using charts and graphs?

Graphs and charts are visuals that show relationships between data and are intended to display the data in a way that is easy to understand and remember. People often use graphs and charts to demonstrate trends, patterns and relationships between sets of data.

## How is graph theory used today?

Graph theoretical concepts are widely used to study and model various applications, in different areas. They include, study of molecules, construction of bonds in chemistry and the study of atoms. Similarly, graph theory is used in sociology for example to measure actors prestige or to explore diffusion mechanisms.

## What do graphs tell us?

Tables and graphs are visual representations. They are used to organise information to show patterns and relationships. A graph shows this information by representing it as a shape. Researchers and scientists often use tables and graphs to report findings from their research.

## Which are the different categories of graph?

Popular graph types include line graphs, bar graphs, pie charts, scatter plots and histograms. Graphs are a great way to visualize data and display statistics. For example, a bar graph or chart is used to display numerical data that is independent of one another.

## Which will best suit representing appendix or link for references?

14) Tables will best suit representing Appendix or link for references. 15) Bar graph is the most widely and commonly used graph. 16) Vertical bar graph is useful when you have two time periods or points of comparison and want to quickly show relative increases and decreases.

## What is not part of storytelling with data?

Story telling with data helps us to visualize and communicate with data in a better way and leads to better understanding with the intended audience. Clutter refers to the visual elements that take up space but do not increase understanding. Eliminating Clutter does not form a part of story telling with data.

## Which are the Preattentive attributes?

Preattentive attributes are visual properties that we notice without using conscious effort to do so. Four preattentive visual properties have been defined: Color (intensity, hue) Form (orientation, line length, line width, size, shape, curvature, enclosure, added marks)
