Hi,
I can generate line charts with smooth curves using d3.js or canvasjs and export it as image. It will be little tough to generate animation in gif, static png or gifs can be generated as the sample.
Pls DM me to discuss further details.
I have 4 years of experience in front-end devlopment using HTML, CSS, JS, jQuery, Bootstrap and AngualarJS. I am proficient programmer in asp.net and php also. I can assure you that I will provide quality work in given time period without any issues. The final code will be delivered with comments and documentation.
Looking forward to work with you,
Kasi
