Tick labels for geographic plots

Currently, the graticules provided by lataxis and lonaxis for geographic plots do not seem to have an option to add corresponding tick labels. For example, cartopy achieves this to produce maps with tick labels like this one:

This would be a nice feature to have in plotly. Apologies if this is actually possible, or has already been requested or mentioned elsewhere, but I couldn't seem to find any documentation on this or any related issues.

まず、地理プロット用の既存のlataxisおよびlonaxisオプションを調査し、関連する軸ラベルのサポートについてPlotlyのドキュメントを確認します。地理プロットで経緯線に対応する目盛りラベルを表示でき、要求されたcartopyの例と同等の動作になることが完了条件です。
