Show HN: A simple tool to convert CSV data into graphs

[devnpatel]

I built a simple tool that converts CSV files into graphs instantly. The idea came from seeing how much time people spend opening spreadsheets or writing code just to visualize data. I wanted something where you can just upload a CSV and get charts immediately. It currently supports quick line and basic chart visualizations from CSV datasets. I’d really appreciate feedback from people who work with data or frequently analyze CSV files.

Hi HN! I'm the maker of Plotiq.

Right now the MVP focuses on the simplest workflow: upload a CSV → instantly generate a line chart.

I built it mainly for quick data exploration without opening heavy tools or writing code. The goal is to make visualizing CSV data as fast as possible.

Currently it only supports line charts and multiline charts, but I'm planning to add bar charts, scatter plots, better styling, and sharing options soon.

I'd love feedback: • What kind of charts would you want first? • What problems do you usually face when visualizing CSV data? • What more features would you like to have?

Thanks for taking a look!

Helpful tool. It will be more better if you add bar chart and scatterplot also. It will he users a lot for getting different charts. And also add graph sharing feature so users can send graph link anywhere without downloading. By the way great and helpful tool.

Thanks for your feedback. I will make this change in V1, this was just mvp. I will surely add this and will give update here after making changes.

Feedback: I have uploaded 90k row data in csv format , but the website freeze in data handling . FIX this problem.

Thanks for trying it and reporting this!

Right now the tool processes CSV data entirely in the browser, so very large files like 90k rows can cause performance issues.

I'm working on improving this — likely by adding better chunked processing and optimization for larger datasets.

And i will increase limit of 5000 rows to somewhat more.

This solves problem for quick graph visualization and best thing is graph is downloadable.

Thanks for trying it!

Glad the quick visualization and downloadable graphs were useful. That was one of the main goals — making it easy to go from raw CSV data to a shareable graph quickly.

If you have any suggestions for additional chart types or features, I'd love to hear them.
