In this article, I explore how to visualize sensor data using Node.js on a Raspberry Pi, moving beyond simple console outputs to create both terminal-based ASCII plots and graphical visualizations. The tutorial guides readers through setting up a CPU load sensor, installing necessary packages like...
Therefore, we often see many types of data visualization videos on station B and Douyin. While we admire the efficient expression of these data visualization videos, I believe many friends are very curious about how these videos are done, right? FFCreator Google and Baidu clicked and searched, ...
接下来,在客户端,我们使用D3.js获取数据并进行可视化,代码示例如下: <!DOCTYPE html> D3.js Data Visualization <svgwidth="600"height="400"></svg> d3.json('/data').then(data=>{ constsvg = d3.select('svg'); constx = d3.scaleBand().range([0,600]).domain(data.map(d=>d...
迁移之前后,我们使用以下Git管理了分支: maindevelopfeature/data-visualizationInitial CommitWork on Data AnalysisAdd new Data VisualizationPrepare for production 完整项目的代码可以在 [GitHub Gists]( 上查看。 性能优化 在Node.js 16中,我们可以利用新特性对性能进行优化,通过以下C4架构图来展示系统优化前后的变化。
这里我们首先引入了Chart.js库,通过Fetch API获取/data路由中的数据,然后生成一个线形图。这个基础示例将您引入数据可视化的初步体验。接下来,我们列出在这个应用中使用的关键函数与方法。 fetch():用于发起网络请求,获取后端数据。 Chart():Chart.js的构造函数,用于创建图表对象。
