Have you heard about data visualizations?

00:17.320 --> 00:22.120
Wondered what a visualization is or why they are so popular or how you can understand

00:22.120 --> 00:27.320
them better, have you asked yourself what is data visualizations?

00:27.320 --> 00:32.200
A data visualization is quite simply a visual representation of data.

00:32.200 --> 00:37.240
In other words, a data visualization shows statistical and numerical data in visual

00:37.240 --> 00:40.680
ways to communicate their meanings.

00:40.680 --> 00:45.040
Visualizations aim to help people make sense of data and to explore it too.

00:45.040 --> 00:50.000
Experts believe representing data in visual ways can help communicate what the data means.

00:50.000 --> 00:54.480
It can also allow people the opportunity to analyze and examine large data sets, which

00:54.480 --> 00:57.240
would otherwise be difficult to understand.

00:57.240 --> 01:00.160
Maybe you have seen or heard the term infographics.

01:00.160 --> 01:05.320
An infographic is similar to a data visualization, but the two things are not the same.

01:05.320 --> 01:09.880
An infographic is designed to tell a particular story to a specific audience.

01:09.880 --> 01:12.200
It might include images or information.

01:12.200 --> 01:14.800
Usually, it doesn't include data.

01:14.800 --> 01:19.800
It might show more design flare than a data visualization.

01:19.800 --> 01:25.480
Here are some examples.

01:26.480 --> 01:32.000
On the other hand, often presents a data set with minimal editing, and it aims to make

01:32.000 --> 01:36.080
the data more accessible than it is in its raw form.

01:36.080 --> 01:41.040
Some data visualizations also aim to make it possible to explore the data on which they're

01:41.040 --> 01:42.040
based on.

01:42.040 --> 01:47.200
A data visualization may have been generated automatically from a big data set such as

01:47.200 --> 01:52.720
with migration in the news, or it may be based on a small data set as in the trials of

01:52.720 --> 01:54.880
a time lord.

01:54.880 --> 01:57.160
Where can we see data visualizations?

01:57.160 --> 01:59.480
The answer is lots of places.

01:59.480 --> 02:05.760
This includes the internet, social media, traditional media, like newspapers and magazines.

02:05.760 --> 02:10.680
On TV, visualizations are often used in the news, for example, during elections or in

02:10.680 --> 02:12.400
sports programs.

02:12.400 --> 02:16.840
You might receive them through the post and campaigning or advertising material.

02:16.840 --> 02:20.960
When graphs or charts are used to convince you of something, or in reports from your

02:20.960 --> 02:24.080
bank pension or other organizations.

02:24.080 --> 02:28.400
Here are some examples of data visualizations that are circulating today.

02:28.400 --> 02:32.800
This is just a small sample from many hundreds to give a taste of what visualizations might

02:32.800 --> 02:35.120
look like and what types of data they represent.
