Well, here is the type of data visualizations that can be chosen depending upon the size and nature of the audience.
TemporalFor a data visualization to be temporal, it should be linear and one-dimensional.
In simpler terms, it represents the lines which can either be unequaled or intersect with each other.
Temporal data visualization includes the following:Scatter PlotsPolar area diagramsTime series sequences and timelinesLine graphsThe main advantage of temporal data visualization is that we are quite familiar with such type of visuals especially in schools and workplaces whenever any explanation is done using charts.
HierarchicalHierarchical data visualizations indicate the ranking and order of various data and objects in a company or organization.
For example, the tree graph with a simple linear path which allows data flow from left to right or top to bottom.
Other Hierarchical data plots consist of the following forms:Ring chartsTree-map chartsSunburst diagram graphsCircle PackingDendrogram charts.
These data visualization forms are most useful where information has to be depicted in clusters.
However, the complexity of these graphs when compared to others is the only backdrop.
NetworkNetwork data visualization allows users to demonstrate the link by connecting various data sets.
Under this network, the users communicate through the intricate networks that link one data set to another.
Few of the common types of network data visualization include –Alluvial diagram chartsNode-link diagramsNetwork diagram chartsWord cloud plotsNon-ribbon chord diagram plotsParallel coordinates plotMatrix charts.
You can count on these visualizations whenever you want to elaborate the connection link between the data sets.
MultidimensionalAs the name suggests, multidimensional data brings two or more elements under consideration.
Multidimensional data visualization is usually known for the most attractive visuals because of the many intersecting layers and datasets.
Multidimensional data visualization consists of the following varietiesSteam graphsPie chartsScatter PlotsHistogramsTimetable chartsStacked area graphsStacked bar graphsMulti-set bar chartsParallel setsVenn diagramsThe above-mentioned charts are the most beneficial as they can break down big data into their fundamental elements.
GeospatialGeospatial data visualizations display information about physical areas.
For instance, geospatial maps which depict regional maps with data marks.
These maps are usually used to reveal information regarding sales or acquisitions that are made over a certain period of time.
Moreover, they can be made visually appealing if they are properly colored coordinated.
Various geospatial visual data types include –Density plotCartogramDot distribution mapChoroplethHeat mapFlow mapConnection mapPolitical campaigns and multinational corporations that want to showcase their market influence to the masses benefit the most from these maps.
Data Visualization TechniquesThe process of representing visual data requires the following techniques to be followed properly that involves –Know the audienceFor every business whether small or large, it is necessary that the audience should be considered primarily.
A chart prepared for a group of school students cannot be used for a group of college students and vice-versa.
Therefore listing down the audience types and discussing it with your colleagues for further progress brings more proficiency and reliability to the project.
Emphasizing on relevant details according to the type of audience is utmost important.
If the audience is new to data visualizations, demonstrate to them using traditional charts such as bar charts or pie charts.
Simple or interactive charts can also be created according to the interest of the audience.
Right chart selectionFor this, it is required to step back from the software program and create a rough draft or sketch on a paper.
Share it with your colleagues and discuss further improvements.
Create it on your computer and keep editing.
If you’re not much familiar with data visualization then it is better to go for classics like bar or line chart.
Progressively, you can try the lesser familiar chart types like bubble charts, dot plots etc.
Create a draft on a computerThe moment you have gathered the rough idea of your visualization, start creating a draft of your visualization on the computer.
You can try various software programs based on your accordance.
Edit the draftYou have to do some hard work in editing your draft as their might be some unwanted things in it.
Various software programs provide in-built borders, lines, and ink which can be unnecessary sometimes.
So, examine each of those features and clean out those which do not have any purpose in your draft.
Another thing that is manageable is outlining the shapes in white to match the background color and remove labels to avoid zigzags around the screen.
Use text to convey the messageGo for those fonts which match with the project’s branding instead of using traditional Microsoft’s fonts.
Subtitles can be added to add a description.
A two-line or three-line detail is considered to be perfect.
Contextual details can be added using annotations with a two-line caption just below it.
Check the size of various texts, for example — Headings should be large and information related to it should be comparatively smaller.
Always remember to keep the size of those texts large that target audience the most.
Use colors to convey the messageColors play an important role in enhancing the charts.
They make the charts more attractive and appealing.
Avoid using default colors from Google or Excel.
Instead, use the color scheme of the chart.
Preview your chart in grayscale instead of printing directly.
Check the improvements required if necessary.
Make sure the colors which have been used can be seen by those having color-vision deficiency.
Use a dark or light contrast for the final message of the chain.
Examine the draftCheck the progress with different tests.
Ask your colleagues to go through the draft and check for some changes or improvements.
The best assessment would be the data visualization checklist where you can examine your draft properly.
Sharing the data visualization chartThis is the final step in which the chart designed is shared across various platforms to check if it can adapt their environment.
These platforms can be presentations, webinars, handouts, and social media.
However, before presenting the chart across different platforms, one needs to keep certain things in mind –If you’re presenting in a conference presentation or webinars, organize the chart into slides.
A blue internet cord can be used for faster connection to run live webinars.
A one-page handout is apt to target the audience with a clear picture of the message to be conveyed.
In the case of social media, make sure the chart is in 2:1 aspect ratio.
Overlapping the facts on photographs can also be done if necessary.
Combine different charts to form a dashboard or an infographic.
Dashboards are used for internal audiences for instance, the board of directors making decisions about the company.
Infographic is used for the external audiences, for instance, to raise public awareness about a particular issue.
Why Data Visualization is Important?Following are the reasons why people should go for data visualization:Make complex data look simpleData visualization techniques are useful in representing only that information which is essential for the target audience.
For instance, pie charts can be used to depict the population of a particular region on the basis of age group.
Big to smart dataData visualization techniques can be beneficial in breaking down big data and converting it into information sensible enough for the target audience.
They can be used to explain complicated content in a simple manner.
Less time, more productivityData visualization techniques consume less amount of time as only relevant information is to be presented instead of the entire content.
Consequently, this leads to an increase in productivity.
Online Data Visualization ToolsFollowing are some third-party online visualizations tools that are available for free to be used by everyone –Tableau PublicTableau GalleryMicrosoft Power BIGoogle Data StudioOpenheatmapLeafletDatawrapperChartbuilderThe Future of Data VisualizationData visualization is marking its entrance in the new era.
It is advancing from art to science with the introduction of next-generation technologies and the evolution of apparent frameworks giving rise to new opportunities.
Majority of data visualizations is two-dimensional.
Neuroscientists are inventing ways to develop a five-dimensional model called a 5-D colorimetric technique.
It is also expected that with new up gradations working methods of the analysts will improve.
They will answer the queries faster and look for more ways to grasp the data creatively.
Hence, it is right to say that “Data Visualization” will be a brand ambassador of innovative data exploration.
