We can often hear big data, as well as big data visualization of such words, which can also be very intuitive, big data technology has been integrated into all aspects of our lives.
Some of the partners who are interested in this field, came to ask the author, said I want to know what is the meaning of big data visualization, specifically what is done, Jinan Computer Learning / will speak in detail, big data visualization is what is the meaning of what is done, specifically what is this topic.
1: First of all, let's first understand, the basic concept of big data visualization.
Data visualization, is the scientific and technical study of the visual representation of data.
This visual representation of data is defined as a kind of information extracted in the form of some kind of summary, including the various attributes and variables of the corresponding information unit, which is mainly aimed at conveying and communicating the information clearly and effectively with the help of graphical means.
2: A big data visualization engineer is responsible for promoting big data visualization products; making constructive visualization products and interaction related suggestions and solutions; responsible for the application of graphical tools and means in the collection of high-quality data to reveal complex information in the data at a glance; analyzing and calculating according to the product strategy and presentation logic; extracting and integrating the presentation data and so on. The data is analyzed and calculated according to the product strategy and presentation logic, and the presentation data is extracted and integrated, etc.
3: big data visualization engineers need to understand and master the core technology of JavaScript language DOM, BOM, Ajax, JSON, etc., can use native javascript to write most of the functional components, in-depth understanding of the object-oriented thinking of javascript and can be applied to the actual project; have Echars, Highcahrts, d3js and other data visualization framework development experience and so on.
