Frontend Developer with experience in D3 JS wanted for custom line chart

Hello friends,

I’m Vagelis and I’m building a product for price comparison. I’m currently using a line chart that displays historical data of grocery prices.
I would like to create a metro map style of stacking lines for the cases that prices of different series overlap. I’ve found this not possible with standard chart libraries that I’m currently using.
I’m looking for a developer that would be able to implement a custom solution using D3 JS and include the line chart in my React app.
Attached for reference: Metro map showing stacked lines the way I want to implement them in my line chart.

Feel free to reach out if you would be able to complete this project.

Thanks in advance, Vagelis
