Data security has never been a more important consideration for consumers or for the businesses they patronize and partner with. It’s also never been more difficult to ensure. Every single day, consumers’ personal, health and financial information is at risk of theft. This can lead to identity theft, and to serious financial ramifications. While military-grade encryption on websites and through smartphone and tablet apps can be an important precaution, it’s just a Band-Aid. More must be done. Blockchains may hold the key to ensuring data security, but how does the technology that underpins bitcoin and other cryptocurrencies ensure data security for consumers and businesses?

Unless you’ve been living under that proverbial rock, you’ve at least heard of cryptocurrency – those digital, non-corporeal monetary units that have the world abuzz these days.

Correlation is a statistic that measures the strength and direction of the associations between two or more variables. Causation, on the other hand, is a relationship that describes cause and effect. “Correlation does not imply causation” is a famous quote that warns us about the dangers of the very common practice of looking at a strong correlation and assuming causality.

How can I plot 2 dimension data with weight?

Any recommendation?

Well said about all visulaization methods. Thank you Abhishek for your valuable points. Can you give the explanation about Sankey diagram?

Any suggestion?

It doesn't make sense to use bar graph in visualizing continuous data, because bar graphs are suitable for count data such as discrete data.

Can anyone suggest an open source software to make scientific diagrams?
