The graphical representation of data and information is known as data visualization. In data visualization, some visual elements like charts, graphs, and maps are used. These elements and other data visualization tools give an easy way and pattern to determine the outliers, trends, and patterns in the data. With the help of tools and technologies by data visualization in Tableau, it has become easy to analyze big amounts of information and data. In addition, it has helped to make data-driven decisions.
Big Data is here & we need to know what it has
Data visualization assists in informing the stories by curating data into an easier form. It would be easy to remove the noise from the data hand and highlight the full use of information with the help of a good visualization.
Nevertheless, it is not as simple as it looks when you talk about making a graph for data look better. It could be said that effective data visualization is a wonderful balancing process between the function and the form. Some plainest graphs could look boring or uninteresting. Sometimes, some wonderful visualization could also fail when it comes to caring for the right message it should speak. You must know that the visuals and data need to work collaboratively; there is a specific way to combine great storytelling with the analysis.
When you think about creating data visualization in tableau, you would be concerned about the right placement of your key data, charts, and graphs. As you are beginning with the visualization, you could feel that you have a lack of knowledge about data visualization.
Here are some of the reasons that can make you feel concerned about data visualization:
- You could be sure when it comes to the placement of each element in your chart.
- To determine your users for the data viz, you could be very unclear.
- It could be difficult to determine where you should put your menu items so that they become more visible
Luckily, some scientists have decided that people go through the images and text in a specific pattern. Once you determine how to organize the data in your visualization, it would be easy to use the standard patterns that could assist users in collecting the data and information quickly.
To create a well-designed and formatted visualization, you need some basic tips to use your knowledge of the visual patterns:
Balance: it becomes necessary to maintain balance when you are ready to place items in your visualization. If too many items are grouped together, it would be hard for people to see what they have carried.
Color: you cannot use some random colors like red can be misleading as it could cause some problems to the viewer to see any alert.
Hierarchy: perhaps you already know about hierarchy as it affects any text outline. You can consider the top level having a Roman numeral, the second level having a capital letter, and the third level has a number. To tell which items are lower or higher on hierarchy, you can determine the position or size in visualization. You do not need to use numbering, as you often do in any written outline.
Repetition: to be familiar with the items in design, the repetition assists people a bit more. As the people might have seen some certain elements already, they could fail to notice the same elements throughout.
- White Space: the use of white space is considered very important for the past decades. The white spaces permit content to do well because your images benefit from sufficient space around the objects present in the visualization.
Data Visualization in Tableau
If you talk about these sought-after skills in data visualization, you might need to talk more about the Tableau certification. Tableau financial services are a known visualization and Analytics tool that is used all around the industry at the moment. For several data and Science related works, many businesses consider this tool as the best.
Due to the drag and drop interface, this tool has become a very convenient tool used. If you want to perform tasks like comparing, analyzing, and sorting, this tool will help a little bit more. It is also compatible with various sources that include SQL server, excel, and other cloud-based data repositories. It can become the best choice for data scientists so far.
Establishing a Connection
You can use this tool to connect different data sources from service and files in a convenient way. It is useful to work on several file formats like TXT, JSON, and CSV. Also, you can get your data imported by servers like Tableau Server, Amazon Redshift, and MySQL. To determine everything about your data, the visualization needs to include more information about the data. If you want your information to be meaningful to your audience, the information required to be considered from their perspectives as well. Reliable data visualization explains the story to the audience by using different languages and ideas that they easily understand.
Things that Make Data Visualization Effective
If you do the data visualization in tableau appropriately, it could have the maximum effects. If the data visualization can easily solve its purposes, you can define it as the right data visualization. If people can easily understand conception through getting queries data displayed, you can determine that your data is working in the correct way. Let us try to collect a little bit more information about the data visualization and things that makes it effective
Data Visualization has many kinds to make new patterns
Temporal: data visualization belongs in a limited grouping match to specific conditions: either it is linear or one-dimensional. The temporal visualization normally features which overlap or stand. They also have a finish and start time. There are several familiar charts that you can identify from the workplace and school, and it would be easy to understand all of them.
Here are the examples that you need to know:
- Scatter plots
- Line graphs
Network: Datasets can connect other datasets deeply and easily. Network data visualization demonstrates their connection with each other within any network. In easy words, showing the relationships between the data sets could be done without going through the wordy explanations.
Instances of Network Data Visualization
To bring a story to your data, you can match and mix the best data by dividing them into a common graph. Hence, you can check to discover in the bulk amount:
- Bar Chart
- Line Chart
- Pie Chart
- Waterfall Chart
- Funnel Chart
- Heat Map
- Box Plot
- Area Chart
When bar chart visualization should be used?
You can use a bar chart due to the below-listed reasons:
- Determine how the see data sets related to one other
- You might not have too many groups
Tips to enhance Data Visualization in Tableau
- To design full impact visualization, it is necessary to keep in mind several rules that can improve your data visualization:
- Comparison: you should include a zero baseline if it is possible.
- Copy: you should not over-explain if the copy is already there.
- Ordering: There should be a logical hierarchy to order data intuitively.
