Hello there! I am Kashif, a skilled website developer with 5 years of experience in JavaScript, WordPress, PHP, HTML, and CSS. I understand that you need to add a functionality to a d3 directed graph app so that new nodes can be added without needing to recreate the whole graph from scratch. When a new node is added, it's connected to the other existing nodes so that they don't need to be updated.
I believe I would be the best fit for this project because of my extensive experience in d3 and related technologies such as graph databases. This knowledge coupled with my commitment to delivering high quality work will ensure that your project is completed quickly and accurately.
I would love to discuss this project in more detail if there is any way I can help make your lives easier throughout the process. Please don't hesitate to contact me if you have any questions or would like more information about me or my work.
