Hi, in Paraguay we have been working with data visualization for public contracts and their finantial execution. Here are some examples:
- Contracts by yean and institution https://www.contrataciones.gov.py/datos/visualizaciones/contratos
- Lifecicly of a contract https://www.contrataciones.gov.py/datos/visualizaciones/etapas-licitacion
- Financial execution in time of contracts of a particular project http://www.mopc.gov.py/mopcweb/BM/IGAP/index.html
Perhaps they might help at least as inspiration
