Data Visualization Tool: Tableau

One of the most beneficial skills to have as a Data Analyst is understanding and using Tableau. Tableau is the best data visualization software, allowing you tvisualize, present and share data. But even if you're unfamiliar with Tableau, you can still learn how to use it effectively.

Data Visualization: Overview

Data visualization is using data (usually numerical) to tell a story in a way that allows people to understand the information and draw conclusions. Data visualization can be used in business, science, politics, marketing, and more. The goal of data visualization is to communicate information effectively through graphical representation.

Data visualization has many uses:

For example, to present numerical information clearly and.

To intuitively give statistical results or other complex data so non-specialists can interpret it.

To provide feedback on the quality of research findings.

To communicate ideas using simple graphics.

Why Data Visualization?

Data visualization is one of the most important aspects of data analysis. It enables us to understand the structure and relationships between different types of data and their meaning in context. Visualization helps us to find patterns and trends in our data, which can be used to make more informed decisions in business.

Visualization also helps us communicate information effectively by providing a visual representation that can be understood by people who need a technical background or are unfamiliar with statistics.

For example, we want to explain why sales are down in our company. In that case, we could create an infographic showing how many orders were placed per day during each month and where they came from. This would help us show the general trend over time and identify any problems in our sales process that need addressing immediately.

Data Visualization Tool: Tableau

A tableau is a tool for data visualization. Tableau helps you turn your data into an interactive, insightful visual experience that helps people answer questions, make decisions, and drive action. With Tableau, you can explore your data and create dashboards to help you analyze your data.

Tableau's easy-to-use interface allows anyone to understand how to use it, whether they're new to analytics or an experienced analyst. In addition, the intuitive drag-and-drop user interface makes it easy for anyone to get started using Tableau.

Why Tableau?

• Tableau provides a wide range of tools for analyzing and visualizing your data. The tool allows you to create interactive dashboards and share them with the world. It's an excellent way for people who work in business intelligence (BI) departments or for sales reps who want to track trends in a specific industry or region.
• Tableau integrates nicely with other business applications, such as Salesforce and Google Analytics, so you can easily connect multiple applications in one place. You can also use Tableau's data connection feature to import data from other applications into Tableau to see how they relate.
• Tableau allows users to create visualizations from their data sets with a drag-and-drop interface and an easy-to-use, intuitive interface for managing the analysis process.
• Tableau also has some other features, such as adding interactive elements like maps or charts that change when you move your mouse over them (for example: showing population density over time). You can also create formulas that calculate values based on variables in your data set.

Terminology in Tableau

A dashboard is a single graphic representation of the state of digital data. It is a visual representation that shows trends, time series, and other information in a format easily analyzed by users.

Data source refers to the data you use to create your dashboard. The dashboard can be made using various data sources, such as financial spreadsheets, graphs, tables, and websites.

A filter is a way of making a subset of data visible in the worksheet. For example, you can use filters to hide or show specific columns, rows, and cells.

A pane is a section of your worksheet that shows some subset of your data but not all of it. For example, you might have a Sales Pane that shows only those records from your Sales table that match the criteria you've set up in your Custom Pane.

A worksheet is a tabular form of data that contains columns and rows, with each column representing a different type of measurement and each row representing an individual entity or observation.

A workbook is an application that enables users to combine sheets into one document for sharing or storing.

A live connection is a connection between your data source and your workspace that you can use to make changes. For example, as you work with your data, you can add, delete, or search for data in real-time. In addition, live connections are useful for creating visualizations that include dynamic content such as text or images.

An extract connection is a map of your data. It represents all the values stored in your data source but has yet to be used in a visualization. Extract connections are helpful when you want to create tableau sheets from existing sources such as Excel files or databases.

While reviewing data visualization tools, Tableau stood above the rest. Their intuitive interface and a rich library of templates and charts available to users made creating striking visualizations fast and fun. With their new feature, Storylines, this tool will continue being a leading data visualization software for years.
