KANATA GC (Visual Data Presentation)
Data visualization is the process of representing data in a graphical or pictorial format, such as charts, graphs, or maps. The goal of data visualization is to communicate information clearly and effectively to users through the use of visual elements, such as points, lines, and bars. It is a key tool in data analysis and decision making, as it allows users to easily identify patterns, trends, and outliers in large sets of data.
The flow from raw data to actionable insights typically includes the following steps:
Gather data from various sources, such as databases, sensors, and external APIs.
Remove any inaccuracies, inconsistencies, or missing values in the data.
Combine data from different sources to form a cohesive dataset.
Analyze the data to identify patterns, trends, and relationships.
Use charts, graphs, and other visual aids to communicate the insights from the data.
Use statistical methods, machine learning algorithms, and other techniques to extract meaningful insights from the data.
Communicate the insights to the relevant stakeholders in a clear and concise manner.
Use the insights to inform decisions, optimize processes, and drive business outcomes.
It's important to note that these steps can vary depending on the use case and the organization's requirements. Also, this process is an iterative one, where you may go back to earlier steps to refine or improve the results
There are many benefits to using data visualization in data analysis and decision making. Some of these benefits include:
Data visualization makes it easier for users to understand and interpret large sets of data. By using visual elements, such as charts and graphs, users can quickly identify patterns, trends, and outliers that may not be immediately apparent in raw data.
Data visualization can be used to effectively communicate information to others. By using clear, easy-to-understand visuals, users can convey complex ideas and findings to a wider audience.
Data visualization can save time and effort by allowing users to quickly identify important information. This can lead to more efficient decision making and problem solving.
Facilitation of data exploration:
Data visualization allows users to explore data in a flexible way and discover insights that would be difficult or impossible to find otherwise.
Better memory retention:
Data visualization can help people to remember information more effectively.
Better decision making:
Data visualization can help decision-makers understand the data and make more informed decisions.
Data visualization can enable multiple stakeholders to understand and contribute to the data analysis process.
There are many different techniques and types of data visualization, including:
These are used to compare the values of different categories or groups.
These are used to track changes over time.
These are used to show the proportion of different categories or groups.
These are used to show the relationship between two or more variables.
These are used to show the distribution of values across a grid.
These are used to show the distribution of values across a geographic area.
These are used to show the hierarchical structure of data.
These are used to show the connections between different data points.
These are used to show the frequency of words in a text.
These are used to show multiple visualizations in one place, to give an overview and allow to drill down.
These are some examples, and there are many other data visualization techniques and tools available, depending on the type of data and the message that you want to convey
Some popular data visualization software include:
Microsoft Power BI
IBM Cognos Analytics
SAS Visual Analytics
Oracle Business Intelligence
