DATA VISUALIZATION 1
Data artists use infographics to display patterns, relationships, and trends in a visual format.

DATA VISUALIZATION 2
Data visualization - Describes technologies that allow users to “see” or visualize data to transform data into a business perspective.
Data visualization tools - Move beyond Excel graphs and charts into sophisticated analysis techniques such as pie charts, controls, instruments, maps, time-series graphs, and more.

‹#›
DATA VISUALIZATION 3
Business intelligence dashboards - Track corporate metrics such as critical success factors and key performance indicators and include advanced capabilities such as interactive controls allowing users to manipulate data for analysis.

‹#›
BLOCKCHAIN: DISTRIBUTED COMPUTING 1
Distributed computing - Processes and manages algorithms across many machines in a computing environment.
© McGraw Hill
‹#›
BLOCKCHAIN: DISTRIBUTED COMPUTING 2
Ledger - Records classified and summarized transactional data.
Blockchain - A type of distributed ledger, consisting of blocks of data that maintain a permanent and tamper-proof record of transactional data.
© McGraw Hill
‹#›
BLOCKCHAIN: DISTRIBUTED COMPUTING 3
Proof-of-work - A requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions (blocks) on the distributed ledger or blockchain.
Proof-of-work has two primary goals:
To verify the legitimacy of a transaction, or avoid the so-called double-spending.
To create new digital currencies by rewarding miners for performing the previous task.

BLOCKCHAIN: DISTRIBUTED COMPUTING 5
Blockchain - Formed by linking together blocks, data structures containing a hash, previous hash, and data.
Genesis block - The first block created in the blockchain.
Hash - A function that converts an input of letters and numbers into an encrypted output of a fixed length.

BLOCKCHAIN: DISTRIBUTED COMPUTING 6
Proof-of-stake - A way to validate transactions and achieve a distributed consensus.

This figure shows an infographic health chart based on age and weight. Age groups include 18–34, 35–49, 50–64, 65–74, and 75+. Low weight. 14 persons belong to 18-34 age group. 1 person each belongs to 35–49, 50–64, 65–74, and 75+ age groups. Normal weight. 9 persons belong to 18-34 age group. 4 persons belong to 35–49 age group. 3 persons belong to 50–64 age group. 1 person each belongs to 65–74 and 75+ age groups. Overweight. 5 persons belong to 18-34 age group. 5 persons belong to 35–49 age group. 4 persons belong to 50–64 age group. 2 persons each belong to 65–74 and 75+ age groups. Obese. 4 persons belong to 18-34 age group. 5 persons belong to 35–49 age group. 5 persons belong to 50–64 age group. 3 persons belong to 65–74 age group. 1 person belongs to 75+ age group.

A rectangle is divided into many smaller rectangles. Each rectangle is color-coded and represents the cost of public sectors and services. For example, the orange rectangle represents grants-in-aid to N D P B’S and its cost is 29,105,000 Euros, the green rectangle represents consultancy and its cost is 10,091,082 euros, and so on.

This diagram displays a centralized ledger: a dropbox, and a decentralized ledger: a Blockchain. A centralized ledger like dropbox includes one stored central copy that is accessed by four participants. A decentralized ledger has a Blockchain by which a distributed ledger is accessed separately by all four participants via the four nodes on the network.

This image shows that a Blockchain is formed by linking blocks like data, previous hash, and hash. Data refers to transactional data sender, receiver, and number of coins.
Previous Hash includes hash of the previous block in the Blockchain. Hash refers to the block’s unique identifier like a fingerprint.

This image shows three blocks in a Blockchain, which is formed by linking blocks like previous hash, and hash. Block 1. Hash: 123AB, Previous hash: 0000 (This is the genesis block; no previous hash). Block 2. Hash: 456CD, Previous hash: 123AB. Block 3. Hash: 789YZ, Previous hash: 456CD.
