Data Visualization and Reporting
Data is not meaningful unless people can understand
it. Collecting and analyzing data are not enough, data has to be presented to
concerned parties. That is the reason data visualization is such important. Here are seven key tips to help turn data into
insights people will understand:
1. Keep the audience and their information needs in mind.
We
have to know who our target audience is and find out good ways to present to
them. It is vital to customize any data visualization to meet the audience and
their information needs. Think of who is in that audience and then think about
the questions they would like answered. Knowing what we are addressing help us
select right data out of tons of data and make it meaningful to audience.
2. Choose
the right chart.
There
are so many different types of charts available in the data visualization tools,
such as bar chart, line graph, pie chart, etc. Bar chart might be the most
common chart type. However, we need to choose the right type depends on what
kinds of information because not all charts are created equal. Some do a better
job than others at displaying different kinds of information. We need to choose the best chart type to
display the information.
3. Go
beyond Excel or PowerPoint templates.
Speaking of data visualization, many people may first think of excel which is a
very nice tool for visualizing data. But when it comes to big data, utilizing
other great tools such as Tableau, Data Miner, would make the life easier. Another
popular visualization tool is PowerPoint, but its built-in templates may not be
doing your data any favors. Instead of trying to get fancy, keep your
visualizations simple and uncluttered to be as clear as possible.
4. Provide context.
The purpose of data visualization is not only showing the data we have in our
data base, but we need to use the data to have storytelling. Making good use of color, size and other
visual cues to provide context and include short narratives that highlight the
key insights. A good visualization will make the user understand what’s going
go with the data, prompt the user to act on the data being presented, which may
be deciding location on a new business, or may be about executing marketing
campaign, or other important decisions making on company.
5. Direct people to the most important information.
A good data reporting should be able to draw people’s attention to significant
points on information and lead people to get insights from the data presented. When
designing data visualizations, use sensory details like color, size, fonts, and
graphics to direct attention to the most important pieces of information would
be a great idea.
6. Axis
labels and numbers should be clear.
Avoid fancy labels and gauges that can get in the way of clarity. Label the
axis of a graph or chart clearly and start at zero—unless you have a strong
reason not to—e.g. when all the data is clustered at much higher values.
7. Provide
interactivity when appropriate.
New generations of data-visualization tools make it possible to build
interactivity into many visualizations that can benefit the end user. But
again, remember that this isn’t a parlor trick, and should be used when
interactivity can clarify, rather than confuse, the presentation of data.
