Starting from the outside of the pie, place strawberries in concentric circles until you reach the middle. Fill in empty spaces with blueberries.
Cut chocolate into small pieces. Heat 1/4 cup heavy cream to a boil.
Pour a tablespoon at a time of the hot cream over the chocolate and mix together until it forms a paste.
Fill a Ziplock bag with chocolate mixture, cut off a bottom corner, drizzle filling over pie. Refrigerate until ready to serve.
