What is the best method for John to share his survey results visually on his website?

Creating a public report is the best method for John to share his survey results visually on his website because it provides a structured and easily accessible format for presenting data. A public report can include graphs, charts, and visualizations that effectively communicate insights drawn from the survey, making the information more engaging and understandable for visitors to the website.

This approach allows for a comprehensive view of the results, ensuring that all relevant findings are included in one place. Visitors can interact with the report at their convenience, which enhances user experience and ensures the information is readily available for reference.

The other options, while they may have their merits in specific contexts, do not offer the same level of transparency and accessibility for data visualization on a website. Email notifications would reach only specific individuals, limiting the audience. Posting results on social media may not provide the depth necessary for understanding the data, and hosting a webinar, though interactive, requires real-time attendance and may not cater to all users who wish to review the results at their own pace.
