` within the `` of `index.html`. This should resolve the immediate issue. I also verified the CSS styling in `style.css` which is already properly configured for a transparent black box with white text and rounded edges.\n\n\n**Addressing the Missing Element**\n\nI've pinpointed the root cause. The `index.html` file lacks the crucial `#tooltip` element. Without it, the hover effect and display will not function. Therefore, my immediate step is to add `

` to the `` element within `index.html`. This will ensure the tooltip is available for the script's `d3.select(\"#tooltip\")` reference. The provided CSS in `style.css` appears correctly configured for a transparent black box with rounded edges and white text.\n\n\n**Resolving the Tooltip Deficiency**\n\nI've determined that the `index.html` file lacks the `tooltip` element, preventing its correct display. This is a critical issue that I will immediately address by adding `

` to the `` within `index.html`. This ensures the script's `d3.select(\"#tooltip\")` reference functions as intended. The associated CSS, notably the transparent black box styling and white writing, is already properly defined in `style.css`.\n\n\n\nI will make the requested changes. I'll start by adding the missing HTML element for the tooltip and adjust its positioning logic to better align with your description. Then, I'll integrate text-to-speech functionality so that the name of the country is spoken aloud when you hover over it.\n\nHere are the planned changes:\n\n```index.html\n```\n\n```script.js\n```\n\n```style.css\n```","cursor","eyJpZCI6ImR5ZHZ5b2dhMzRqOF90ZHRhNjQxIn0","token","included",[180],{"_64":181,"_100":66,"_182":-5,"_183":55,"_184":55,"_185":55,"_186":95,"_187":95,"_188":95},"project_permissions","user_id","can_edit","can_delete","can_edit_members","can_view","can_list","can_participate","routes/browser/layout","actionData","errors"]
