Data visualization is the graphical representation
of information and data.
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.
In the world of Big Data, data visualization
tools and technologies are essential to analyze
massive amounts of information and make data-driven
decisions.
In this video, we will explore what is a Donut
Chart in Data Visualization.
A donut chart is essentially a Pie Chart with
an area of the centre cut out.
Pie Charts are sometimes criticised for focusing
readers on the proportional areas of the slices
to one another and to the chart as a whole.
This makes it tricky to see the differences
between slices, especially when you try to
compare multiple Pie Charts together.
A Donut Chart somewhat remedies this problem
by de-emphasizing the use of the area.
Instead, readers focus more on reading the
length of the arcs, rather than comparing
the proportions between slices.
Also, Donut Charts are more space-efficient
than Pie Charts because the blank space inside
a Donut Chart can be used to display information
inside it.
