The document discusses data visualization techniques for visual data mining. It defines key terms like visual, visualization, and visual data mining. Visual data mining uses visualization techniques to discover useful knowledge from large datasets. Benefits include faster understanding of problems, insights, and trends in data. Different graph types like bar charts, histograms, pie charts and scatter plots are suitable for different purposes like comparing values or showing relationships. Effective visualization requires arranging data clearly, identifying important variables, choosing the right graph, keeping it simple, and understanding the audience.
Data visualizations make huge amounts of data more accessible and understandable. Data visualization, or "data viz," is becoming largely important as the amount of data generated is increasing and big data tools are helping to create meaning behind all of that data.
This SlideShare presentation takes you through more details around data visualization and includes examples of some great data visualization pieces.

Data Representation
Introducing Visual Encoding
Data representation is the act of giving visual form to your data.
Viewers: When perceiving a visual display of data, it is decoded using the shapes, sizes, positions and colors to form an understanding
Visualizers: Doing the reverse through visual encoding, assigning visual properties to data values
Comprised of a combination of two properties
Marks: Visible features like dots, lines and areas
Attributes: Variations applied to the appearance of marks, such as size, position, or color.

Pie Charts
Compare a certain sector to the total.
Useful when there are only two sectors, for example yes/no or queued/finished.
Instant understanding of proportions when few sectors are used as dimensions.
When you use 10 sectors, or less, the pie chart keeps its visual efficiency.

Bar Charts/Plots
Ordinal and nominal data sets
Compare things between different groups or to track changes over time
Measure change over time, bar graphs are best when the changes are larger

Data visualization is an interdisciplinary field that deals with the graphic representation of data. It is a particularly efficient way of communicating when the data is numerous as for example a time series.
Data Visualisation Design Workshop #UXbneCam Taylor
In this workshop we’ll explore both the art and science of communicating information graphically in the digital world.
With lots of great examples and a hands-on team exercise, the session is intended to make us think about how we can convey information more clearly and efficiently in our apps, presentations, reports, emails and other forms of communication.

Data visualization of Big Data analytics nandini patil
Data Visualization is the art and science of making data easy to understand and consume for the end-user. It is the last part of the Data life cycle of data analytics. ppt is based on book Data analytics written by Anil Maheshwari
The art technique of data visualizationUday Kothari
Decision making based on information has been the single most important objective of a data warehousing or big data pursuit. No matter how big, fast and varied data are generated and processed; decision makers are only concerned with the consumption of its end result – data visualization.
Data visualization simply means representing data in a visually appealing manner to enable understanding of the context in which we operate. Data visualization is a “moment of truth” that stems from a data management initiative. It is a very linear process of decision making; and hence, critical to its success. However, data visualizations also possess the potential to put an end to such initiatives; especially, when they are either heavily biased on just the design or contain information overload.
This webinar on the art and technique of data visualization focuses sharply on the one thing that matters most to qualify for effective data visualization: the truth that comes out from data. We have facilitated the discussion with the help of our 3D framework: Design, Discovery & Data.
After registering, you will receive a confirmation email containing information about joining the webinar.

Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Editor's Notes
1)Understand the problem domain faster
Human can understand and process visual information faster. Because of that user and understand and analyze problem domain more efficiently than it is present in as text and numbers. Most reports that’s typically populated with static tables and charts fail to make information vivid for those who view it
2) Efficient data assimilation
Quantity of data doesn't matter in data visualization. It is allowed to create images, animations that enables users to receive vast amounts of information regarding operational and business conditions. Data visualization allows decision makers to see connections between multi-dimensional data sets and provides new ways to interpret data through the use of maps, charts, and other rich graphical representations.
3) Fast access to business insight
With data visualization you can see how you did in past and how new changes you have made affect on business with minimum effort
4)Fast Identification of trends
5)New business intelligent tools provides facilities to unlimited drill down view them in different perspective
