please compute a bar chart

A$$bar$$chart$$could$$show$$the$$decline$$in$$warehousing$$costs$$and$$the$$rise$$in$$forecasting$$accuracy$$for$$Sephora$$between$2021$and$2023,$highlighting$$the$$ERP$$system$\text{'}$s$$

effectiveness.$$For$$instance$,$one$$bar$$could$$represent$$pre$-$ERP$$values$(2021),$while$$the$$second$$bar$$would$$reflect$$post$-$ERP$$results$(2023).$

$1$st step:

Sephora$$s$$ERP$$optimized$$global$$operations$$by$$reducing$$warehousing$$costs$$by$20\%$and$$improving$$forecasting$$accuracy$$by$22\mathrm{.}5\%.$The$$system$\text{'}$s$$integration$$across$$its$$supply$$chain$$enabled$$better$$inventory$$control$$and$$demand$$prediction$,$contributing$$to$$overall$$operational$$efficiency$,$illustrated$$through$$calculated$$improvements$.$
