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

6 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

9 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
1 Bubble 
0 Chart
A bubble chart displays  
three variables by using  
circles of different sizes 
and  colors to represent 
the  relationships between 
them
1 Network 
1 Graph
A network graph, or a 
node-  link diagram, 
illustrates  relationships 
between  entities as 
nodes (points)  and their 
connections as  links 
(lines or arcs)

2 Map
A choropleth map uses 
color  or patterns to 
represent  data values 
across  geographic regions, 
 providing insights into  
spatial patterns
1 Sankey 
3 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.
1 Word 
4 Cloud
A word cloud displays 
words  from a text 
dataset, where  the size or 
color of each  word 
corresponds to its  
frequency or importance.
