What is the best way to store and present data dynamically in D3.js?

Currently, I'm engaged in a project involving my Raspberry Pi that focuses on a sensor collecting data continuously. My objective is to save this data in a specific format such as SQL, CSV, JSON, or any other suitable option, and then present it visually on a basic page using D3.js.

I've considered several approaches, including utilizing SQLite or MySQL to develop a database and retain the data. Subsequently, I may convert this SQL database into a JSON or CSV file for displaying purposes. However, I'm still seeking an effective solution for storing, converting (if required), and presenting the data dynamically without consuming excessive resources or time.

Could someone point me in the right direction?

Answer β„–1

If you're not looking to utilize the functionality of a database and simply need to write data to a single table from a single process, I suggest opting for a CSV file as it will result in the smallest storage space. Once you have all the data, you can always convert the CSV file into JSON format for further processing.

Answer β„–2

My recommendation is to start by building databases in SQL and then transforming them into flat or nested JSON structures (I personally find flat JSON easier to manipulate). After that, you can seamlessly integrate them into your d3 file. This method has been effective in my work and I believe it would be beneficial for others as well.
