javascript visualization

In the Internet industry, the word information visualization should be no stranger. ~ ~ In recent years, people have a number of tedious information through the visualization of the graphical display of the example, the emergence of more and more! Now let's talk about the topic systematically. Visualization of information Information

Because the next to do the seller background data vertical and horizontal revision, the data visualization of this piece of research and experience of the collation, with you to share the data visualization commonly used in five ways, hope to give you the development of ideas. 　Concept Through the use of graphical means, clear, efficient and effective transmission and communication information. From the u

First, the outsetFirst of all here to thank my company, because the company needs above the new (wonderful) needs, let me lucky to learn some fun and interesting front-end technology, front-end technology fun and more practical I think it should be a number of front-end data visualization this aspect, the current market data visualization framework dazzling, For example: D3.js, Hightcharts.js, Echarts.js ..

This two-part article series will demonstrate a visualization technique that helps extract information from the data that has business value, and this article is the first part of the series. You'll see how to use Scalable Vector Graphics (SVG) and open source D3 JavaScript libraries to create visual representations that can be viewed through the browser, conveying information through shapes and colors. I'l

Article Description: The recent study of "information visualization" requires that the scope of research be defined first. The recent study of "information visualization" requires that the scope of research be defined first. The definition of information visualization has been studied by colleagues before, this article simply extracts the wiki defini

First of all, I would like to thank Miss Lin Feng for choosing me. @ Kener-Lin Feng (1) Next I will introduce Baidu's data visualization components echarts and zrender.As we all know, the arrival of the big data era not only brings challenges but also opportunities, but it is only a start. The big data era will have a major impact on our lives. As Victor may-schenberger, author of The Big Data age, said, "Today, data has become a commercial capital an

In the task list of the Baidu front-end Technical College There is a task that requires JavaScript to achieve a visual sorting algorithm, it is interesting to study a little bit, would like to achieve bubble sorting algorithm and fast sorting algorithm visualization, But the quick sort is a bit difficult to visualize, so it's time to give up.Bubble Sort PrincipleBubble sort we should all be strangers, right

Data Visualization and D3.jsData Visualization Data visualization is a topic for how to better present data. After the emergence of big data, it becomes more important and urgent. Previously, using excel for column charts, pie charts, and line charts was one of the most commonly used data visualization methods. On the

Visualization of dataData visualization is a topic of how to better visualize data, and it becomes more important and urgent after big data emerges.Previous use of Excel for histograms, pie charts, line charts, etc. is one of the most commonly used data visualization methods, while on the web side, using popular ExtJS, Fusioncharts, Jfreechart, or relatively less

daily statistical analysis of small and medium-sized enterprises, half a bucket of sub-water, limited capacity, other levels can be bypassed: Get data: I plan to capture the investment and loan data of XX financial website from the internet for use as the data source. Basically, data in each dimension and format is available for later operations to read data: here, I will divide the obtained data into xls, csv, SQL, and pandas DataFrame data for separate operations to clean and organize data in

Learn about graphical calculations for the components used to draw various permutations The 1th part of this two-part series outlines the combined use of SVG and D3, providing some basic examples of creating browsing data visualization representations of social media. Part 2nd will describe the steps for arranging or laying out different graphic components in SVG graphics. You will learn how to use D3 powerful graphics to compute the placement of com

Gnuplot In this article, we will conduct a survey on many popular Linux data visualization tools and further discuss some of them. For example, does a tool provide a language for numerical calculation? Is this tool interactive or does it provide a batch processing mode for independent operations? Can I use this tool to process images or digital signals? Does this tool provide language binding to support integration with user applications (such as Pyth

Linux Data Visualization ToolThere are a number of applications for graphical visualization of data on Linux, from simple 2-d drawings to the-to-date cartography, to scientific graphics programming and graphical simulations. Fortunately, there are many open source implementations of these tools, including Gnuplot, GNU Octave, Scilab, MayaVi, and Maxima. Each tool has its own pros and cons and is designed fo

FrontierThrough the previous section on the Python combat data visualization of the Pygal module (Basic) Learning, we have a preliminary understanding of the use of Pygal module, this section will be a practical project to deepen the use of Pygal module. The JSON-formatted population data can be downloaded from the Web and processed using JSON modules, and the Pygal module provides a map creation tool for beginners, which we will use to visualize demo

Select sort (Selection sort)Select Sort is now the smallest in a series of arrays, put it in the first position of the array, then select the second small one and place it in the second position.If the unordered array is a, the first round is compared to the size of a[0] and a[1], if A[0]>A[1], then two interchanges, otherwise not exchanged. This gets the a[0] is the smaller that number.Then a[0] and a[2] are compared, if a[0]>a[2], then two exchanges, otherwise do not exchange. This gets the a[

with the GGPLOT2 in the R language, it seems that two packages are used and the likelihood is developed by the same person! The original author also said on GITHUB that the PYTHON library will no longer be updated! However, ggplot2 is really a drawing artifact, which is almost the only reason I am still using the R language. Therefore, matplotlib is required no matter which library you want to use. Although his syntax is complex, he is flexible. you can draw almost any image you want. Here we

Webstorm+webpack+echartsEcharts Feature IntroductionEcharts, a pure Javascript chart library that runs smoothly on PCs and mobile devices, is compatible with most current browsers (Ie8/9/10/11,chrome,firefox,safari, etc.) and relies on lightweight Canvas class libraries Zrender provides intuitive, vivid, interactive and highly customizable data visualization charts.In Echarts 3, more rich interactivity and

the server side, listening to client requests, providing data services.2, linking to a MongoDB instanceDo not close the MongoDB instance, open a new command-line tool, enter MONGO, the command starts MONGO Shell,shell will automatically connect to the local (localhost) MongoDB instance, the default port is 27017:MongoThe MONGO process is to construct a JavaScript Shell that interacts with the Mongod process to manage the MongoDB database according to

Because at present in the big Data class product, the interface always needs to use the design language to explain some very fictitious, the abstract concept, therefore will inevitably study the information visualization. Before seeing a lot of peers in this respect of the summary and sharing, but found that the content is similar, almost all from abroad some related books and materials. So here I want to talk about the experience of this project, the
