Introduction
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
visualization:

01 Line Chart
A line chart displays
data points connected
by a line, often used to
show trends over time or
continuous data.

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

06 Area Chart
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

07 Histogram
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

08 Treemap
A treemap represents
hierarchical data using
nested rectangles, where the
size of each rectangle
corresponds to a specific
attribute or value.

09 Box Plot
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
10 Bubble Chart
A bubble chart displays
three variables by using
circles of different sizes and
colors to represent the
relationships between them
11 Network Graph
A network graph, or a nodelink diagram, illustrates
relationships between
entities as nodes (points)
and their connections as
links (lines or arcs)

12 Choropleth Map
A choropleth map uses color
or patterns to represent
data values across
geographic regions,
providing insights into
spatial patterns
13 Sankey Diagram
A Sankey diagram visualizes
the flow of data or resources
through interconnected
pathways, often used to
show energy flows, migration
patterns, or customer
journeys.
14 Word Cloud
A word cloud displays words
from a text dataset, where
the size or color of each
word corresponds to its
frequency or importance.
