Data visualization refers to the presentation of data in a graphical manner. It enables decision-makers grasp complex concepts or identify new data patterns by having a visual view of data analytics. With interactive visualization, you can enhance the idea of data visualization by using technology to convert data into charts and graphs.
Alibaba Cloud DataV is an effective data visualization tool that allows business decision-makers to conveniently understand data patterns, relationships, and trends.
Is data visualization a new concept? Why is it important?
Data visualization is not new. Businesses have been generating reports using maps, graphs, and charts as a way to summarize data. Data visualization is important mainly because of the way the human brain is designed to process information. It is always much easier to grasp information by supplementing text-based reports with graphs and charts.
For businesses in particular, data visualization cuts out the cumbersome process of data comprehension and offers users the ability to process and make sense of data using visually-presented and interactive dashboards. Data visualization tools allow users the opportunity to analyze trends interactively, helping businesses to conveniently identify relationships and draw inferences from data.
Despite the significant advantage of data visualization for businesses, it comes with its own set of challenges.
Taking into consideration the importance of data visualization and the challenges that businesses face while attempting to use data visualization, Alibaba Cloud introduced its data visualization tool – DataV.
In this tutorial, we will install Metabase on an Alibaba Cloud ECS CentOS 7 server to achieve data visualization.
Metabase is an open source application for visualizing your database and get insights from it. Metabase provides an intuitive and easy to use web-based interface for running queries on a database without writing a SQL statement. It works with almost all popular databases such as MySQL/MariaDB, Postgres, Mongo, SQL Server, Druid, H2, SQLite, and Oracle, etc. Data can be obtained in raw tables or beautiful graphs or charts. Metabase refers the queries to a database as questions. It lets you save the questions once asked, saved queries can be repeatedly executed to get the answers quickly. It also lets you create dashboards in which you can add multiple questions to get all the important insights in one place. Dashboards are auto-refreshed every time and can also be shared among your team members.
This tutorial is a port of How to install Metabase on Ubuntu 16.04. In this tutorial, we will install Metabase on CentOS 7 server. We will use PostgreSQL to host the Metabase database. We will also set up Nginx as a reverse proxy and secure the Metabase instance using Let's Encrypt SSL.
You can follow the "Quick Start Guide" to create the instance and steps to connect to your instance. This tutorial assumes that you have created your Alibaba instance and "192.168.0.101" is the public IP address assigned to your CentOS instance. You have also configured "metabase.example.com" to point to your CentOS instance. Once you have connected to your instance via SSH, run the following command to update the repository cache and the base system.
This article describes the various features of QuickBI. We will be analyzing and visualizing a use case to help you create compelling data stories with QuickBI.
In the previous "Deciphering Data to Uncover Hidden Insights" series, we covered three topics of data analytics, including:
For me, "the best vision is insight." As per the saying, I like to walk you through in the process of deciphering data to uncover hidden and valuable insights for your business. In this article, I want to share how to visualize the data to tell compelling data stories according to your business scenario in Alibaba Cloud's Quick BI data visualization tool.
"A picture is worth a thousand words "- When you're attempting to comprehend the information from the data and to discover relationships between your data, which might include thousands or millions of variables in front.
Visualization becomes inevitable in the world of Big Data; Data visualization tools and technologies are essential to analyze massive amounts of information and it allows us to make data-driven decisions.
Data visualization refers to the pictorial representation of data. Information could be visualized in many ways including infographics, charts, graphs, and maps, each of which can offer a specific insight. Visual elements pave the way to see and understand patterns, outliers, and trends.
At its core, data visualization has three purposes:
"Data Visualization plays an inevitable role in the modern business world." Data visualization ought to be insightful, efficient, appealing, and in several cases interactive too.
The basic purpose of the visualization or the canvas is to inform a meaningful information to the consumer. Envision the basic forms of visualizations like Tile or Bar or Pie, everybody is acquainted with these visuals and can quickly infer the intended point they represent. Since we're currently aggregating information and displaying it pictorial format it should convey the message that the aggregated information is telling us which becomes harder with a large amount of data.
This article uses an official example to explain how to use the Istio functions of collecting, querying, and visualizing telemetry data.
In our previous articles, we have demonstrated how to deploy an application in the Istio environment with an official example, as well as explored how to configure intelligent routing and distributed tracing with Istio.
This article continues to use this example to explain how to use the Istio functions of collecting, querying, and visualizing the telemetry data.
Prometheus is an open source system released by CNCF. It provides the real-time monitoring, alerting, and time series database (TSDB) functions for the cloud native applications.
First, refer to the metrics and log configurations defined in the official documentation to create a new_telemetry.yaml file.
Run the istioctl command to create the new configuration, as shown below:
istioctl create -f samples/bookinfo/new_telemetry.yaml

Data visualization refers to the techniques used to communicate data or information by encoding it as visual objects contained in graphics. By using data visualization, data can be displayed through a dashboard intuitively and understandably. This course can help the data scientists learn how to create a large panel using Alibaba Cloud's DataV.
Data visualization capabilities are very important. A beautiful and clear charts can help you understand the data intuitively when you explore and analyze data, Data visualization also plays an important role in your interactions with customers, and it helps you communicate the quantitative characteristics of the data.
Through this course, you will learn what is python visualization and how to use python visualization tools to generate plots to visualize data.

This provides you with visual and transparent data analysis and decision-making capabilities to keep your website security.
Currently, the WAF data visualization service provides the following two visual screens for your choice:
WAF Real-time Attack and Defense Situation Screen
WAF real-time attack and defense situation screen is updated every second. It displays current day's website visit and overall interception situations for all your websites that protected by WAF. This screen focus on displaying the stability of the website service and the quality of the network service.
This section introduces table structure visualization in Data Management Service (DMS).
When creating or arranging new and existing tables, you may need to learn the structure of all tables. The traditional method uses commands to view and copy structures, table by table, or uses data visualization tools to display the structures and capture screenshots.
You can use the generate documents feature of DMS to quickly generate the structures of all tables in the database. You can then view the structures online or export the structures to Word, Excel, or PDF files.
DataV is a powerful yet accessible data visualization tool, featuring geographic information systems allowing for rapid interpretation of data to understand relationships, patterns, and trends. All packed into a user-friendly interface.
Delivering analytic capabilities once reserved for professional analysts, Quick BI allows you to perform data analytics, exploration, and reporting on mass data with drag-and-drop features and a rich variety of visuals. Quick BI enables users to perform data analytics, exploration, and reporting, and empowers enterprise users to view and explore data and make informed, data-driven decisions.
