Hello everyone, I am new here and happy to join this Plotly community. I study data visualization and interactive dashboard with Plotly and Dash, and I want to learn how to present business data in clear and useful charts. I try many examples with time series, bar charts, and scatter plots, and I find this forum very helpful because many members share real code and best practice for Python and R usage. I have a little experience with Excel and simple charts before, but I want to improve with Plotly because interactive graph help me to explain data story to others.
In my work sometimes I get business data from different sources and I need show them in dashboard for team review. For example, we discuss data from partners who outsource construction estimating services and want to show cost trends and resource allocation in a report. I think this kind of real business data can be good example to practice with Plotly, but I am not sure how to clean and organize data before visualization. Can someone share tips for data prepping and best Plotly chart type when showing multiple categories and time trends together? Also, if there are sample templates for business dashboards you recommend, I would like to see them. Thanks in advance for help!
