A good starting point for the aspiring developer would be to refine the flowchart by ensuring the correct use of flowchart symbols. Each part of the process should be accurately represented with the appropriate symbols, such as decision points, processes, and input/output indications, rather than just using pill shapes for the beginning and end of the flow.
Additionally, they should consider the user experience when the app fails to acquire weather data; notifying users about data acquisition failures could help manage user expectations and prompt them to take action if necessary. Incorporating feedback loops for data updates and displaying any outdated information can also enhance the functionality and usability of the app.
Overall, focusing on proper flowchart representation and user feedback mechanisms would provide a solid foundation for further development of the weather app idea.
