HTML/JS Interactive Chart Canvas Development
Budget: $250 – $750 USD
I'm looking for a skilled web developer with expertise in HTML, JavaScript, and libraries like OpenCV or TensorFlow. The project involves creating a website where I can upload an image onto a canvas. The JavaScript should be capable of identifying various types of Barton Charts (specifically 24 hour, 7 day, 8 day, 16 day, and 31 day).
Key Functions:
- The JavaScript needs to find the center of the chart (the center of the black circle), the 0% mark inner circle, and the 100% outer circle.
- After identifying these components, the script should compute one of the arc angles and draw a line from the center of the chart to the 100% mark along the arc.
- A draggable circle should be placed at the end of the line, allowing me to click and drag the arc around the circle, pivoting around the center of the chart.
- More chart example are available upon request.
Ideal candidates should have a strong background in web development, specifically with HTML and JavaScript, and have experience with image processing libraries. The goal is to create an interactive, user-friendly chart manipulation tool.
