D3.js
D3.js (also known as D3, short for Data-Driven Documents) is a JavaScript library for producing dynamic, interactive data visualizations in web browsers. It makes use of Scalable Vector Graphics (SVG), HTML5, and Cascading Style Sheets (CSS) standards. It is the successor to the earlier Protovis framework. Its development was noted in 2011, as version 2.0.0 was released in August 2011. With the release of version 4.0.0 in June 2016, D3 was changed from a single library into a collection of smaller, modular libraries that can be used independently. Context There have been various previous attempts to bring data visualization to web browsers. The most notable examples were the Prefuse, Flare, and Protovis toolkits, which can all be considered as direct predecessors of D3.js. Prefuse was a visualization toolkit created in 2005 that required usage of Java (software platform), Java, and visualizations were rendered within browsers with a Java plug-in. Flare was a similar toolkit fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mike Bostock
Michael Bostock is an American computer scientist and data visualization specialist. He is one of the co-creators of Observable and a key developer of D3.js, a JavaScript library used to produce dynamic, interactive data visualizations for web browsers. He also contributed to the preceding Protovis framework. Biography Bostock pursued a PhD in computer science at Stanford University In 2009, Bostock was advised by Jeffrey Heer at Stanford. As a part of Stanford's Visualization Group (VisGroup), they created Protovis, a Javascript-based visualization toolkit. The toolkit relied on native browser technologies and included an abstract representation layer that made it difficult to debug. In 2011, Bostock, Heer, and Vadim Ogievetsky announced D3.js, a successor to Protovis. D3 stood for data-driven documents and allowed data objects to be bound directly to the browser's Document Object Model instead of requiring interaction with an intermediate layer. This change allowed for easier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Data Visualization
Data and information visualization (data viz/vis or info viz/vis) is the practice of designing and creating Graphics, graphic or visual Representation (arts), representations of a large amount of complex quantitative and qualitative data and information with the help of static, dynamic or interactive visual items. Typically based on data and information collected from a certain domain of expertise, these visualizations are intended for a broader audience to help them visually explore and discover, quickly understand, interpret and gain important insights into otherwise difficult-to-identify structures, relationships, correlations, local and global patterns, trends, variations, constancy, clusters, outliers and unusual groupings within data (''exploratory visualization''). When intended for the general public (mass communication) to convey a concise version of known, specific information in a clear and engaging manner (''presentational'' or ''explanatory visualization''), it is t ...

Bleeding Edge Press
Bleeding, hemorrhage, haemorrhage or blood loss, is blood escaping from the circulatory system from damaged blood vessels. Bleeding can occur internally, or externally either through a natural opening such as the mouth, nose, ear, urethra, vagina, or anus, or through a puncture in the skin. Hypovolemia is a massive decrease in blood volume, and death by excessive loss of blood is referred to as exsanguination. Typically, a healthy person can endure a loss of 10–15% of the total blood volume without serious medical difficulties (by comparison, blood donation typically takes 8–10% of the donor's blood volume). The stopping or controlling of bleeding is called hemostasis and is an important part of both first aid and surgery. Types * Upper head ** Intracranial hemorrhage — bleeding in the skull. ** Cerebral hemorrhage — a type of intracranial hemorrhage, bleeding within the brain tissue itself. ** Intracerebral hemorrhage — bleeding in the brain caused by the rupture of ...

Comma-separated Values
Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores Table (information), tabular data (numbers and text) in plain text, where each line of the file typically represents one data record (computer science), record. Each record consists of the same number of field (computer science), fields, and these are separated by commas in the CSV file. If the field delimiter itself may appear within a field, fields can be surrounded with quotation marks. The CSV file format is one type of Delimiter-separated values, delimiter-separated file format. Delimiters frequently used include the comma, tab-separated values, tab, space, and semicolon. Delimiter-separated files are often given a ".csv" filename extension, extension even when the field separator is not a comma. Many applications or libraries that consume or produce CSV files have options to specify an alternative delimiter. The lack of adherence to the ...

JavaScript Framework
A web framework (WF) or web application framework (WAF) is a software framework that is designed to support the development of web applications including web services, web resources, and web APIs. Web frameworks provide a standard way to build and deploy web applications on the World Wide Web. Web frameworks aim to automate the overhead associated with common activities performed in web development. For example, many web frameworks provide libraries for database access, templating frameworks, and session management, and they often promote code reuse. Although they often target development of dynamic web sites, they are also applicable to static websites. History As the design of the World Wide Web was not inherently dynamic, early hypertext consisted of hand-coded HTML text files that were published on web servers. Any modifications to published pages needed to be performed by the pages' author. In 1993, the Common Gateway Interface (CGI) standard was introduced for interfa ...
