highcharter

Highcharter depends on Highcharts, which requires a separate paid license for commercial or governmental use, adding cost and legal overhead not covered by the R package's open-source license.

Charts rely on the Highcharts JavaScript library being loaded in the client environment, which can complicate deployment in offline systems or applications with restricted external dependencies.

If Highcharts lacks a specific chart type or feature, Highcharter cannot provide it, unlike more flexible R libraries that allow custom extensions or integration with other JavaScript tools.

While basic charts are straightforward, advanced customization often requires understanding both R syntax and the underlying Highcharts JavaScript API, which can be challenging for users unfamiliar with web technologies.
