Data Visualization
Tableau , Power Bi and Plotly
They say a picture is worth a thousand words, and this is especially true for data analytics. Again going word by word ; what do you think about when you hear ‘Data Visualization’ ? It is simple, Visualization of Data is what you would think off.
According to tableau data visualization is the graphical representation of information and data . Imagine how tough it will be to make non-technical audience understand about the data insights in technical terms, this is where Visualization comes into the picture. It provide an accessible way to see and understand trends, outliers, and patterns in data making it easier to present it to the audience.
Why Data Visualization is so important?
Data visualization helps us to understand what certain data is telling us, presenting it in a way that’s accessible to a range of audiences—not just data experts but to some non-technical audience too. It’s the perfect way to bridge the gap between your expertise as a data analyst or data scientist, and those people who can use or act upon the insights you discover.
It helps you to tell a meaningful and impactful story, highlighting only the most relevant information extracted from the dataset. Visualization helps us to give a quick brief/summary or some important insights of a large dataset.
The importance of data visualization is simple: it helps people see, interact with, and better understand data. Whether simple or complex, the right visualization can bring everyone on the same page, regardless of their level of expertise.
