Record-triggered flow is a feature that allows administrators to automate actions that occur when a record is created or updated. Record-triggered flow can perform actions such as updating fields, creating records, sending emails, or invoking Apex code. Record-triggered flow can be used to update the account checkbox field 'Opportunity Created' when at least one related opportunity has been created

Change sets are tools that allow administrators to move customizations such as fields, page layouts, profiles, permission sets, etc. from one Salesforce org to another. To use change sets, administrators need to establish a deployment connection between a source org (such as a sandbox) and a target org (such as production). Then, administrators can create an outbound change set in the source org that contains the components they want to deploy, and upload it to the target org. In the target org, administrators can view and validate the inbound change set before deploying it to their org. Reference: https://help.salesforce.com/s/articleView?id=sf.changesets.htm&type=5

To embed a report chart on a record page, you need to use a lightning component that displays report charts. You can filter the component visibility by setting conditions based on record fields, user attributes, or device type. In this case, you can filter the component visibility by matching the Account ID field on the report chart with the Account ID field on the record page. This will ensure that only the relevant data for that account is shown on the chart.
