To create flexibility for users to plot network graphs with the provided data, we will demonstrate how to make use of an npm package Highcharts to plot Network Graphs in Angular.<\/p>\n\n\n\n<p>In this blog, we will cover:<\/p>\n\n\n\n<ul><li>What is Highcharts?<\/li><li>What is HighChart Angular Wrapper?<\/li><li>What is Network Graphs?<\/li><li>Hands-on<\/li><li>Conclusion<\/li><\/ul>\n\n\n\n<h2>What is Highcharts?<\/h2>\n\n\n\n<p class=\"has-text-align-justify\">Highcharts is a JavaScript-based charting package that adds interactive charting functionality to web applications. Highcharts has a large number of charts to choose from. Line charts, spline charts, area charts, bar charts, pie charts, and other types of graphs are examples.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">To know more, refer to:<\/p>\n\n\n\n<p><a href=\"https:\/\/www.workfall.com\/learning\/blog\/how-to-plot-bar-charts-in-angular-using-npm-package-highcharts\/\">How to plot Bar Charts in Angular using npm package Highcharts?<\/a><\/p>\n\n\n\n<h2>What is HighChart Angular Wrapper?<\/h2>\n\n\n\n<p class=\"has-text-align-justify\">HighChart Angular Wrapper is an open-source Angular component that provides elegant and feature-rich HighCharts visualizations within an Angular application and can be used alongside Angular components seamlessly.<\/p>\n\n\n\n<h2>What is Network Graphs?<\/h2>\n\n\n\n<p class=\"has-text-align-justify\"><a href=\"https:\/\/www.highcharts.com\/docs\/chart-and-series-types\/network-graph\">Network graphs<\/a> (force-directed graphs) are mathematical structures (graphs) that visually depict the relationships between points. The graph shows the relationships between the various topics. The relationships between the entities are shown as lines, and the entities are shown as nodes. The other interconnected nodes receive an assigned weighted factor, and the graph is a force directed by applying weight (force) from the node edges. The graph represents the weight as forces acting on the nodes to determine where they should be located on the plotting area of the graph. The Network Graph can be used in a variety of ways, including to display relationships between people, places, businesses, and products.<\/p>\n\n\n\n<h2>Hands-on<\/h2>\n\n\n\n<p class=\"has-text-align-justify\">In this hands-on, we will begin with an online compiler for angular called <a href=\"https:\/\/stackblitz.com\/\">StackBlitz<\/a> which gives us the flexibility of an already created folder structure. We will be using this compiler to create flexibility for users to plot network graphs with the provided data. We will first begin with exploring the files created by default and then alter the folder structure as per our need. Providing proper naming conventions for the file, we will create a new HTML file, we will alter the input parameter value, and change the template URL to point to the newly created HTML file for the child component.<\/p>\n\n\n\n<p class=\"has-text-align-justify\">We will then install the highcharts and the highchart angular wrapper to be able to plot the network graphs. Post that we will import the highcharts component into the app module file. To test out the configuration of highcharts we will then create a network graph utilizing the various different parameters offered by highcharts and have a look at the different features offered.<\/p>\n\n\n\n<h3>Required installations for the process:<\/h3>\n\n\n\n<ul><li><strong>HighChart: <\/strong>It is a JavaScript charting library that is used to enhance web applications by adding different interactive charting capabilities.<\/li><li><strong>HighChart Angular: <\/strong>It is an Angular wrapper that provides rich Highcharts visualizations within an application in the different components.<\/li><\/ul>\n\n\n\n<p class=\"has-text-align-justify\">To perform the hands-on on a local machine, you can follow the steps mentioned in the below link of the original angular documentation to create a new project and then follow the hands-on steps shown below.<\/p>\n\n\n\n<p><a href=\"https:\/\/angular.io\/tutorial\/toh-pt0\">https:\/\/angular.io\/tutorial\/toh-pt0<\/a><\/p>\n\n\n\n<p class=\"has-text-align-justify\">To follow the steps we performed, you can navigate to the link below.

Post that we imported the highcharts component into the app module file. To test out the configuration of highcharts we then created a network graph utilizing the various different parameters offered by highcharts and had a look at the different features offered. We will come up with more such use cases in our upcoming blogs.<\/p>\n\n\n\n<p><strong>Meanwhile\u2026<\/strong><\/p>\n\n\n\n<p class=\"has-text-align-justify\">If you are an aspiring Angular Developer and want to explore more about the above topics, here are a few of our blogs for your reference:<\/p>\n\n\n\n<ul><li><a href=\"https:\/\/www.workfall.com\/learning\/blog\/how-to-enhance-ux-by-managing-api-requests-using-angular-resolver\/\">How to enhance UX by managing API requests using Angular Resolver?<\/a><\/li><li><a href=\"https:\/\/www.workfall.com\/learning\/blog\/how-to-plot-bar-charts-in-angular-using-npm-package-highcharts\/\">How to plot Bar Charts in Angular using npm package Highcharts?<\/a><\/li><li><a href=\"https:\/\/www.workfall.com\/learning\/blog\/how-to-export-datasets-into-csv-format-using-angular-with-filesaver\/\">How to export datasets into CSV format using Angular with FileSaver?<\/a><\/li><\/ul>\n\n\n\n<p>Stay tuned to get all the updates about our upcoming blogs on the cloud and the latest technologies.<\/p>\n\n\n\n<p><strong>Keep Exploring -&gt; Keep Learning -&gt; Keep Mastering&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"has-text-align-justify\">At <a href=\"https:\/\/www.workfall.com\/\">Workfall<\/a>, we strive to provide the best tech and pay opportunities to kickass coders around the world.
