I ran java -XX:+UseG1GC -Xmx2g -Xms32m -jar app.jar 10, but where should I see the memory footprint graph?

Make sure you are using OpenJDK12+ and add options that enable vertical scaling. More details can be found at the blog article https://jelastic.com/blog/elastic-jvm-vertical-scaling/
