1) Definition of Data visualization-
Representation and presentation of data to facilitate understanding(Kirk, 2019, p. 29)
Data visualization is the representation of data or information in a graph, chart, or other visual format. It communicates relationships of the data with images. This is important because it allows trends and patterns to be more easily seen. With the rise of big data upon us, we need to be able to interpret increasingly larger batches of data. (Import.io, 2019)
The field of data visualization combines both art and data science. While a data visualization can be creative and pleasing to look at, it should also be functional in its visual communication of the data. (Nediger, 2020)
2) Key Components of Data Visualization-
Following are the Key components of Data Visualization,
a) Visual Representation- This will involve making decisions on how you will like to portray the data collected.This can be in the various forms,
Charts – Bar charts, Line charts, Pie charts
Table – Pivot table
Summarization Bar – Can be used in financial application when you want to see summary of the amount spent in a specific month/year/day.
b) Presentation- Presentation of the data is how do we package up the final product/Data graph.
c) Facilitate Understanding- Making it easy to understand for the audience who will be reading and consuming this data.
3) What techniques do I hope to learn from this course?
I would like to learn as many data visualization tools (Example- Tableau, SAS Business Intelligence, Google Data Studio) as I can which will help me analyze massive data and make data driven decisions to improve my company’s business/processes.
Would like to learn some techniques like how can we make a data graph dynamic this will help to automate reporting when the data is refreshed real time.
