impossible even if the image is slightly complicated. However, when creating a data visualization project with complex interaction logic, the Code complexity of this method will increase with the scale of the interaction logic, and bring about many unexpected program conflicts-all of which are the same reason as the web development field before MVC or the software crisis in 1970s. People of insight had long been surprised by this problem. As a result

[D3.js data visualization practices] -- (1) Draw gridlines and d3.js Grids We often use regular charts (histograms, line charts, and so on) to present data. To clearly indicate which value range of the data on the number axis, the value is directly indicated in the rectangle and point. In addition to this method, you can also use a grid with pale tones as the bac

technology.D3.js is an excellent data visualization library that allows us to quickly and easily transform data into graphics. However, before starting a follow-up tutorial, first of all, I hope you don't misunderstand d3.js: D3.js is not a graphical drawing library Many people are amazed at this point,

You still have to write five prefix statements in one breath for the same attribute, to ensure compatibility, as shown below (in this program, we use D3 to zoom in and out the DIV, and actually use css3 for processing ): 1234567 D3.select ("Div "). style ({"transform": "Scale (" + config. scale + ")", "-WebKit-transform": "Scale (" + config. scale + ")",

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.

for this project, they are all for the final visualization service. I strive to balance visual attractiveness with user interaction, allowing users to explore and understand the subject's trends without guidance. The diagram I started with was stacked blocks, and I realized that simple line drawings were sufficient and clear. I use D3.js for visualization, whic
