When to use a bar chart for data visualization?

Bar charts are great for comparing several different values, especially when some of these are broken into color-coded categories. To illustrate the difference between this and a line graph, let’s now take the same information as above and revisualize it as a bar chart:

How are pie charts used in data visualization?

A pie chart represents one static number, divided into categories that constitute its individual portions. When you use one, you’ll represent numerical amounts in percentages. When you sum up all of the separate portions, they should add up to 100%. These are especially helpful in digital marketing, as you can use them to show a breakdown of:

What are the guidelines for evaluating prevalence studies?

In this note, the guidelines for evaluating prevalence studies arise from criteria applicable to community surveys. The validity of prevalence studies is a function of sampling, measurement, and analysis. Answers to the following questions (see box on 38) can serve as criteria for assessing these features.

How is the prevalence rate of cancer calculated?

A prevalence rate is the total number of cases of a disease existing in a population divided by the total population. So, if a measurement of cancer is taken in a population of 40,000 people and 1,200 were recently diagnosed with cancer and 3,500 are living with cancer, then the prevalence of cancer is 0.118. (or 11,750 per 100,000 persons)

When to use column charts in data visualization?

Usually, it makes sense to use column charts for side-by-side comparisons of different values. You can also use them to show change over time, although it makes sense to do this when you want to draw attention to total figures rather than the shape of the trend (which is more effective with a line chart).

Why are interactive maps used in data visualization?

With technology advancements, content on maps and the maps themselves became digital, interactive, and more appealing as they’re incorporated in data analysis and reporting. Seeing location data mapped and included in visualizations has both enhanced understanding by more audiences and offered a valuable, new context.
