the Tweet Heatmap project https://github.com/fossasia/fossasia-loklak-tweetheatmap shows tweets on a map using a heat map visualization. Currently it is not transparent which time frame was used to select the tweets. Your task is, to add a time slider to select the date for the map. This could i.e. select a single day or a larger period, it's up to you. To select a specific time frame for the tweets in the search result, use the time modifiers 'since' and 'until' like in this example: http://loklak.org/api/search.json?q=spacex%20since:2016-01-03_23:10%20until:2016-01-04_23:20&timezoneOffset=-120 The time modifier works only if you submit also the timezoneOffset, see this line as an example hot to get that value: https://github.com/loklak/loklak_server/blob/master/html/index.html#L92 To complete the task, send a pull request to https://github.com/sevazhidkov/fossasia-loklak-tweetheatmap and get it accepted by it's maintainers sevazhidkov
