Data visualization is the graphical representation
of data to facilitate understanding and analysis.
There are various types of data visualization
techniques, each suited for different types of data
and insights. Here are some common types of data

data points connected
by a line, often used to
show trends over time or
continuous data.

using rectangular bars of
varying lengths, commonly
used to compare categorical
data.

9. Heatmap
05
A heatmap uses color-coded
cells to represent values
within a matrix, providing a
visual summary of data
patterns and relationships

10. Area Chart
06
An area chart is similar to a
line chart but with the area
beneath the line filled,
emphasizing the cumulative
total or distribution over
time

11. Histogram
07
A histogram presents the
distribution of a continuous
variable by dividing it into
bins and displaying the
frequency or proportion of
observations within each bin 1

12. Treemap
08
A treemap represents
hierarchical data using
nested rectangles, where the
size of each rectangle
corresponds to a specific
attribute or value.
Group 1
Group 4 Group 2 Group 3
Subgroup 1 Subgroup 2 Subgroup 3
Subgroup 8 Subgroup 9

13. Box Plot
09
A box plot displays the
distribution of a numerical
variable through quartiles,
outliers, and other summary
statistics, providing insights
into the data's spread and
skewness

14. Bubble Chart
10
A bubble chart displays
three variables by using
circles of different sizes and
colors to represent the
relationships between them

15. Network Graph
11
A network graph, or a node-
link diagram, illustrates
relationships between
entities as nodes (points)
and their connections as
links (lines or arcs)

16. Choropleth Map
A choropleth map uses color
or patterns to represent
data values across
geographic regions,
providing insights into
spatial patterns

17. Sankey Diagram
13
A Sankey diagram visualizes
the flow of data or resources
through interconnected
pathways, often used to
show energy flows, migration
patterns, or customer
journeys.

18. Word Cloud
14
A word cloud displays words
from a text dataset, where
the size or color of each
word corresponds to its
frequency or importance.
