TypeError Object does not support this property of method msg on IE8 に遭遇しました。

ノードとリンク（つまり、グラフ）を描画するためにjavascriptのprotovisを使用しています

ソースは次のとおりであり、私は断固として無知です。

ヒントはありますか？

スクリプトタイプtext/javascript + protovis "は有効なMIMEタイプではありません。これにより、IE 8（および私が疑う他のブラウザー）は関連するスクリプトブロックのコンテンツを完全に無視するため、エラーはtopology.jsまたは無視されたスクリプトで宣言または初期化された識別子にアクセスしようとしているページ内の他の何か。

IEのエラーメッセージには行番号が付いています。それが何であるか、どこから来たのかをアドバイスし、適切なコメントを付けて、スクリプトまたはHTMLファイルのどこを参照しているかを特定してください。
