Best to use gnuplot, which has many decades of development behind it's code base + many examples available.<br />
<br />
Trying to recode gnuplot in some other language like Java, makes very little sense.<br />
<br />
Best to call gnuplot from your code, by having your code emit a gnuplot script, then execute it, targeting the output in some directory, then referencing the output images.<br />

If your goal is to embed many graphs in Web pages, then <a href="http://www.graphviz.org/" rel="ugc">http://www.graphviz.org/</a> will probably provide more flexibility, as you can produce graphs as light weight SVG snippets.<br />
<br />
With SVG (vector based graphs), you'll end up with graphs which can scale onto any device (mobile or desktop), keeping text sharp (no pixilation).

Web Components are a set of standards currently being produced by Google engineers as a W3C specification that allow for the creation of reusable widgets or components in web documents and web applications. The intention behind them is to bring component-based software engineering to the World Wide Web. The components model allows for encapsulation and interoperability of individual HTML elements. Support for Web Components is present in Chrome and Opera and is in Firefox (with a manual configuration change). Microsoft's Internet Explorer has not implemented any Web Components specifications yet. Web Components consist of 4 main elements: Custom Elements, Shadow DOM, HTML Imports and HTML Templates.

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
