In-Depth Information
Multi-dimensional View:
This layer should supplement
the metrics displayed in the top layer with additional data.
Analytical tools must be built into this layer in order to allow
users to perform computational analysis on data.
Detailed View:
This layer should facilitate users to view reports
pertaining to individual transactions (e.g., invoices, shipments, etc.).
Over the past several years, infographics have caught the fancy of business
users. Infographics are visual representations of information, implying
that sets of data are displayed in a unique way that can be seen, rather
than read. These visualizations should not be left up to interpretation; it
should instead be designed in a way that provides a universal conclusion
for all viewers.
Here are some useful data visualization approaches you should follow when you
start designing your data visualizations.
Line Graphs
A line graph shows the relationship between two variables. They are most often used
to show changes or trends over time. Line graphs, if shown as stacking lines, display
comparison of multiple items over the same time period. Figure

aspects of growth associated with an IT company over a continuous span of time.
