Line Chart Goal
A weekly step count line with a dashed reference line marking a 10,000-step goal.
Line Chart Goal is an open-source mobile chart from suiss/uim, drawn with react-native-svg for React Native and Expo, with SwiftUI and Jetpack Compose versions built from the same design tokens. The @esuiss/uim CLI copies its source into your project, so you own the code.
