Final answer:
A declarative solution for customizing a community page to show a report chart involves using a CMS or platform with pre-built components to specify the desired outcome. For example, one could use Salesforce's built-in tools or a CMS plugin to add and configure the chart without writing code.
Step-by-step explanation:
A declarative solution typically involves specifying the desired outcome without explicitly programming the steps to achieve it. In the scenario where a community page needs to be customized to show a report chart, a declarative solution might involve using a content management system (CMS) or a platform that allows users to customize pages with pre-built components.
For instance, if the community page is hosted on a platform like Salesforce, you could use Salesforce's report and dashboard functionalities. You would create a report, generate a chart and then use the built-in tools to add this report chart to the community page. The platform's declarative interface would allow you to select the report and chart without writing any code.
If you're working with another CMS, you could look for plugins or modules that provide reporting capabilities. You would install the plugin and configure it to display the data needed for your community page. This approach is also declarative because you are not programming the feature; you are configuring it.
