Data Visualization FAQs
What is Data Visualization?
Data visualization is a general term that encompasses different technologies, tools, methods, and services that can produce a visual representation of your data. These visual representations help to demonstrate important trends in your data by using graphs and charts. They make the results of your data analysis clearer and more digestible for less data-savvy readers. Data visualizations can be a one-time project or ongoing. You can create automatically refreshable reports to have access to your data at any time
What are some examples of Data Visualization?
With data visualization, you can create comparisons and show relationships between two or more trends. You can draw attention to patterns in your data, for instance, the repetitiveness of some user activity on your website. You can demonstrate how those patterns and relationships develop over time. Data visualization can also produce charts that illustrate more complex concepts, such as processes and hierarchies. These can help you to catch important developments in your data. Last but not least, you can use data visualization to depict geographical data and demonstrate the distribution of patterns and numbers according to region.
What does a Data Visualization project comprise?
Most data visualization projects will begin with some initial data preparation: connecting to the data source, replacing or rotating a few columns, calculating new columns, and so on. Next, you can start building single charts. In the last step, you can create dependencies between these charts, allowing you to sort and filter data quickly and make your visualizations more interactive. On top of that, depending on the tool you are using, you can embed the results on your website, prepare them for sharing, or turn them into presentation slides.
Why do you need outstanding Data Visualization?
Whether you are an individual proprietor or represent a company or any other organization, data visualizations are the most effective way to communicate with your business partners or make an unforgettable impression during a conference. Supplemented by clever and well-designed charts, your presentation will garner attention during any event, including currently widespread online meetings. Apart from this, data visualizations make your business more transparent for yourself and allow you to make business decisions faster. They replace flat and boring tables: a picture says more than a thousand words
What Data Visualization tools are available?
The list of data visualization tools grows continuously, but a few have established themselves as market leaders. They include the well-known Microsoft Excel, data visualization veteran Tableau, Microsoft Power BI, Qlik Sense, and the popular programming language D3.js. There are also many niche tools tailored to very specific purposes, such as visualizing only time-series data. When choosing the most suitable tool for your needs, remember to check whether it allows you to easily share results and can connect to any data source
How do I find the perfect Data Visualization seller?
If you already know which data visualization tools you want to use and what the scope of data preparation is, you can restrict your search to sellers who possess the appropriate skills. If you are still unsure which technology is the right one for you, look for someone who offers consulting services on top. A data visualization specialist must be familiar with several technologies, but a certain degree of specialization is normal and even a good sign. And, as always, a positive candidate score plays a crucial role.
