Global Visualizations of Risk Ratings for Human Rights in AppSheet

Many years ago I developed a herokuapp site to depict an array of context-specific human rights risks for companies investing in new countries (https://nomogaia.herokuapp.com/). HerokuApp won't let me upload new CSVs anymore, though, so the data is outdated now. I've moved the whole spreadsheet into Google Sheets, and an intern has started to move it into AppSheet, but there's no visual interface now. I'm hoping that the rating scores can be color-coded, and maybe countries themselves could be visualized (isn't there a mapping function in AppSheet?).
