2) Connecting your data:

Data depends on your file format(aka extension). For example if you have excel spreadsheet. Click Excel ->> Select the .xlsx file. If it is a .csv file, you need to connect as a Text file.
[[INSERT IMAGE HERE]]

For example, I opened a .csv file in tableau for Connect. This is the preview,
[[INSERT IMAGE HERE]]

> Please inspect your data if it's properly connected or not.

Now, Go to Sheet 1 as Highlighted orange in the screenshot above. After you click sheet1. Here is the preview of the sheet 1 window. Now we can start visualizations

Basic of Visualizations:

Before Actually creating awesome visualization we need to know at least about Measures, Dimensions,Fields and certain grammer of graphics like shapes, sizes, relative layouts, co-ordinate system, hue,density etc. Below are the resources that can be useful to understand the tableau Vocabulary (Excerpted from Silas Bergen's Course Page: DSCI 310 )

Before we investigate this view, a few important facts about

Tableau vocabulary:

“Fields" are what Tableau calls “Variables.”

For example: Country; Population; Year

...these are all “Fields”in Tableau-speak.

Discrete vs Continuous

 Discrete fields will lead to HEADERS, or DISCRETE BINS. Discrete fields, and their pills, are BLUE.

 Continuous fields will lead to CONTINUOUS AXES. Continuous

fields, and their pills, are GREEN

Dimensions vs Measures

 Dimensions are NOT AGGREGATED.

 Measures are fields that by default are AGGREGATED when visualized (summed,

averaged). It makes sense to perform arithmetic operations

on measures, but not on

dimensions.

Tableau is super useful for visualizing all sorts of the datasets. Below are the resources to consult if you want to make a basic scatterplot onto a map or any sort of map based visualization.

Dr. Silas Bergen Course Page: Scatterplots and Maps

After you've completed the basics , you can dig into the tutorial from Tableau official documentation about making Maps in Tableau.
