aryas1ngh/spark-ranking-iiitd ? reverse-engineered prompt

Build me a web app called SPARK that helps people compare computer science departments using publication data from DBLP and IRINS, instead of only the usual small set of conferences.

I want a clean frontend where someone can pick an institution and year range, then see the department ranking, publication counts, and the conference and journal breakdown behind the score. It should feel transparent, so the user can understand how the ranking is calculated and what sources were used.

Also set up the backend so it can load the seed data, pull in the publication data, and serve the ranking results through a simple API. Make sure it’s safe, works locally out of the box, and handles bad inputs gracefully. If anything about the ranking rules or data source format is unclear, look up the current docs online and make a reasonable choice that fits the project description.
